Answer:
2848
Step-by-step explanation:
The cost function is ...
c(n) = 44144 +9.25n
The revenue function is ...
r(n) = 24.75n
You want revenue to equal cost (the break-even point).
c(n) = r(n)
44144 +9.25n = 24.75n
44144 = 15.50n . . . . . . . . . subtract 9.25n
44144/15.50 = n = 2848 . . . . . divide by the coefficient of n
The publisher must produce and sell 2848 books to make production cost equal to sales.
