Problem 103 Hard Difficulty

The table lists poverty-level income cutoffs for a family of four for selected years. Use the midpoint formula to estimate the poverty-level cutoffs (rounded to the nearest dollar) in 2012 and 2014.

\text { Year } & \text { Income (in dollars) } \\
2011 & 22,350 \\
2013 & 23.550 \\
2015 & 24,250


$2012: \$ 22,950 ; 2014: \$ 23,900$

So in this question, were given the poverty level income cutoffs. So we have in 2011 that income cut off to be 22,350 in 2013 to be 23,550. And in 2015 to be 24,000, 250 and we're asked, or the income levels but 2012 and 2014. So if you look at the years, we basically see that 2012 is the midpoint between 2011 and 2013 and 2014 is the midpoint between 2013 and 2015. So let's use our midpoint formula. Or am the specs one plus next to over to why one close? Why? To over to to calculate the values for 2012 and 2014. So in 2012 since when you told was the midpoint of 2011 and 2013 we have the value in 2012 to be when you to 3 50 close. Why to which is 23 my 50 for her to, And that's equal to. And it's true. That was $950 in 2012. So that's the answer to the first part of your question. Now, in 2014 we take the midpoint of 2013 and 2015. So you take 24 to 0 plus 23 by 50 over to, and we get 23,000 $900. And that's the answer for 2014? Yes, of this. Is there the answers to the two apart?
