Answer:
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)
