can serve it this one, it says. And how many years, from two thousand one to two thousand eight&#x27;s inclusive to the sales of ABC megastores exceed the average of the annual sales during that period? Okay, so we&#x27;re looking for when the average but the sales and exceeded the average. We want the sails of that year. You two be greater than the average. Okay, so now let&#x27;s go out and first find the opera. It&#x27;s so they don&#x27;t give it to us. But according to this chart over here that we just have to add up all of these points and divide that by the total number of years, which is eight, because it&#x27;s from two thousand one to two thousand eight. So then we&#x27;ve got four plus six plus seven plus seven plus five is nine plus eight plus ten. So those are all the points from the chart, and they were going to divide that number by eight. If we do that, we should get seven. So we want to know when the sales of that year exceeded seven. So two thousand won is four so four million. So we know that that doesn&#x27;t exceed seven two thousand two doesn&#x27;t exceed seven, two thousand three and two thousand four at seven, where we wanted to exceed seven. So again, that doesn&#x27;t work. Two thousand five is at five million, so that doesn&#x27;t work. Two thousand six, though, is at nine million, so we know that nine million exceeds seven million. So that one works. Two thousand and seven is at eight million. So again, that exceeds seven. So that works on. Then two thousand eight is up ten million, so that exceed seven to that works. So in total, we&#x27;ve got one, two, three years.

So this one says. In two thousand ten, the total sales of ABC mega stores were exactly the same as in two thousand eight. However, compared with two thousand eight in two thousand ten, sales of kitchen appliances and TV&#x27;s were each up by five percent, and the sales of computers decreased by ten percent. Which of the following statements must be true? Okay, so let&#x27;s go ahead and write out the sails for two thousand ten. So we know that kitchen appliances and TV&#x27;s were up by five percent each. So kitchen appliances were forty percent in two thousand eight. But if we went up by five percent, it must not be forty five percent. And then for the TVs. We know that it used to be twenty, and if we went up by five, we know it should be twenty five. And then it says that the computers went down, but ten percent, so it used to be twenty five, but now it&#x27;s going to be ten percent. Okay, so then that&#x27;s going to look through. The answer traces, it says. In two thousand ten, the sales of TV&#x27;s were greater than the sales of computers. Well, the sale of TV&#x27;s was twenty five percent and the sales of computers is ten percent. So we know that that one works so well. Keep that up. So then for be, it says in two thousand ten, the sales of miscellaneous items were less than in two thousand eight. Well, we know that kitchen and TV, each one up by five a computer decreased by ten, which means, like the overall, should not have changed because overalls something to increase by ten and something decreased by ten. So then the kids the miscellaneous should be the same as in two thousand eight. So we know that that&#x27;s not true, so that for sea it&#x27;s us. In two thousand ten, the ratio of the sales of kitchen appliances to the sales of TV&#x27;s was greater than it had been in two thousand eight. Okay, so for looking for the ratio of a kitchen back to TV, you can say forty five percent by twenty five percent. So this is in two thousand ten, and we can compare that to the kitchen and TV of two thousand eight, which was forty two twenty. This one is going to be one point of point one eight her one point eight and then this one is going to be, too. So we know that this ratio is actually bigger, so C is also false. D is on, if then statements, which we know it doesn&#x27;t belong. This is an assumption, and so, typically assumptions are going to be the answer, and we know that it says in In twenty ten, two thirds of the computer sold for laptops and the rest were desktops. When the sales of laptops were twice a sales of just tops. Well, we don&#x27;t know that because the prices might have been different. And we don&#x27;t know that specifically because they didn&#x27;t give us the breakdown of the prices the laptops versus step desk tops, so we couldn&#x27;t assume that&#x27;s true. Mme. So the correct answer has to be a

were given to data points about the year and the number of J. C. Penney stores. And we can use those two data points to find the equation that relates them. And our variables are t for the number of years and or for the year number and end the number of stores. So let&#x27;s start with our Slope 1067 minus 1078 divided by seven minus three. And that gives us negative 11 4th negative because the number of stores is going down. And then let&#x27;s use our point slope form. Why minus y one equals M times X minus X one and weaken substitute. If we want to use the first point, it doesn&#x27;t matter which. But if we do, we can substitute 1078. And for why one? We have our slope and we can substitute three and four x one. We&#x27;re going to simplify this equation, distribute the negative 11 4th and then we&#x27;re going to add 1078 to both sides. Let&#x27;s see what that is as a decimal. So we have 1078 plus 33 4th 1086.25 And now if we want to use the variables for the problem, we had n for the number of stores and we had tea for the year. So there&#x27;s a linear equation that models the situation. Now we&#x27;re going to use that model to predict the number of stores in 2012 and 2014 2012 would be t equals 12 so we can substitute that into the equation. They gave 11 4th times 12 let&#x27;s 1086.25 and we get 1053.25 So approximately 1053 stores and then for the year 2014 will do the same thing will multiply negative 11 4th by 14 and we add 1086.25 and we have and is 1047.75 So that would be approximately 1048 stores. Whether or not these answers air reasonable depends on a lot of other factors that we may not be able to predict, such as about the economy. And an example of that is right now as I speak, it&#x27;s the year 2020 and we&#x27;re in a pandemic and a lot of stores are closing, and I think JC Penney is in real trouble. So this model that we found here is probably not accurate anymore, and it may not have been accurate in the year 2012 or 2014 either.

this question is asking us to find the average rate of change in dollars per year millions of dollars per year for the sales. Um, and we&#x27;re gonna look for a question A from 2001 to 2002. So says it&#x27;s $1,000,000 million per year. We needed to the change in the dollar amount divided by the change in the year. So another way to think about this is Slope would be the same. His average rate of change. So in 2001 the sales was 243 million in 2000 to the sales was 249 million. So that change and why was up six. And that change and ex was up one. That was $6 million for one year. So I divide us out and we get an average rate of change for $6 million per year. Question Be wants us to go from 2001 to 2004. So again changing Why to 49 minus 2 43 over change in x 2004 minus 2001. So that is six, and that is 36 divided by three is too. The label here. This was millions of dollars and this was year, so we&#x27;ve got the average rate of change of two million per year.

this question asked us to answer the given questions involving Gap and their operation of Nelly 3000 clothing stores involving their net sales. For part A. What? We knows that we&#x27;re looking for the change in net sales between 2008 and 2010 which means we&#x27;re taking 14 5 to 6. The sales in 2008 minus 14 660 which is the sales and 2010. As you can see the increased, which means you end up with a negative number of negative 1 34 This is in terms of millions of dollars. This would be the solution to part a now moving on to Part B. We know we&#x27;re looking for the average rate of change, which means we have 14.5 to sex minus 16 019 and we know that we&#x27;re going to be dividing this by 2008 minus 2005. Because we&#x27;re looking at these two years, conversely, and this is equivalent to negative for 98. So this is the average rate of change in sales, and this is again in terms of millions of dollars per year. This is the unit for this problem. It is a word problem for part C. We know that we&#x27;re looking to see the average rate of change in net sales. We know it&#x27;s positive on this one year interval. Therefore, we have 14 60 minus 14 19 7/20 10 minus 2000 and nine. This is equivalent to 463 over one, which is 463 millions of dollars per year. Again, we have our units for this quote.

okay, here. I&#x27;ve drawn just a rough sketch of some of the graph that we see in this problem. Be sure to look in your book for the entire graph. And the point of this problem is to figure out between which two years sales increased by the greatest amount. And even though there are numbers on the Y axis, I didn&#x27;t use those numbers. I found that the greatest increase would be represented by the segment with the steepest slope. So greatest increase steepest slope. So then you look through the different sections of the graph. You see, I&#x27;ve drawn a few of them. This one, this one and this one. And you, of course, you look at all of them in the graph on the one that&#x27;s the steepest is right here between the year 2009. In 2010 Alternately, you could estimate the number the new miracle value for each of these years on. You could subtract each time, and you could figure out the amount of increase between one year and the next
