Anna is considering writing and publishing her own book. She estimates her revenue equation as R=6.37x, and her cost equation as C=10,071+1.08x, where x is the number of books she sells. Find the minimum number of books she must sell to make a profit.

The minimum number of books she must sell to make a profit is 1904.

Step-by-step explanation:

Anna is considering writing and publishing her own book. She estimates her revenue equation as R = 6.37x, and her cost equation as C = 10,071 + 1.08x, where x is the number of books she sells.

So, the condition for no loss-no gain is, C = R

⇒ 10071 + 1.08x = 6.37x

⇒ 5.29x = 10071

⇒ x = 1903.78

Therefore, the minimum number of books she must sell to make a profit is 1904. (Answer)
