Solve the problem.A publisher spends 70,000 on a book for development, editing, and advertising. It costs the publisher per copy at the printer. Find the linear cost function to publish a book. If the publisher charges
per copy, how many books must be sold to break even? (Round to the nearest unit.)
A. C(x) = 24.05x + 70,000 break-even = 5647 B. C(x) = 70,000x + 1.94 break-even = 1500 C. C(x) = 1.94x + 70,000 break-even = 2693 D. C(x) = 1.94x + 70,000 break-even = 3166
