All right.
00:01
So to begin here, before i put anything directly into excel, i'll go over the information that we're given.
00:07
So we're told that our fixed cost, it's going to be $160 ,000.
00:16
We're told that the variable cost is roughly $6 per book.
00:28
And we're told that the price of the book is going to be roughly $46.
00:37
So in that case, we can model profit being price or the price times the number of sales.
00:48
So 46x minus the fixed cost, 160 ,000, minus the variable cost.
00:57
So we know it's $6 per sale or $6 per book.
01:01
So we do 46x minus 160 ,000 minus 6x.
01:04
Or we can simplify that to just 40.
01:08
X minus 160 ,000.
01:13
So we'll have our x values and then our profit, where we're told that we want to vary demand, or the number of sales, from 1 ,000 to 6 ,000 in increments of 200.
01:28
So we'll do things above plus 200.
01:37
Let's see.
01:41
We wanted to go up to 6 ,000.
01:45
So i need to go a little bit further.
01:48
I've gone just a bit too far, so let me just delete those last two.
01:53
There we go.
01:54
Now the profit equation, as i said, it's 40 times the thing, oops, 40 times the thing to the left minus 160 ,000.
02:06
Now i'll just double click on the green box to fill this out.
02:10
So we can see that the break -even appears to occur in the interval just at the end of 3 ,800 to 4 ,000.
02:24
Now, to apply the goal seeker part for the next part of the problem, i'll actually make a slight adjustment where i'll include a cell where it's representing the variable cost at $6 a book and just make the slight change here that the equation should be 46 ,000, minus the cost per book times number of books sold...
