Question

PLEASE HELP ME!

Anna is considering writing and publishing her own book She estimates her revenue equation as R = 6.56x and her cost equation as C = 10.063 + 1.09x where x is the number of books she sells. Find the minimum number of books she must sell to make a profit

Anna must sell atleast ? books to make a profit.

Answer 1

Explanation:

In order to make a profit R > C

So let's make those equal first

R = C

`6.56x = 10.063 + 1.09x`

Let's get X alone by subtracting 1.09x from both sides.

`5.47x = 10.063`

Next we divide by 5.47

`x = 1.83`

Rounding up to 2, looks like Anna needs to only sell 2 books to start making a profit
