Answer:
3012 books
Step-by-step explanation:
Let y = number of books produced and sold
Total cost = Fixed cost + Variable cost = 32379 + 10.75*y
Total sales = 21.50*y
Set these equal to each other and solve for y
21.50*y = 32379 + 10.75*y
10.75*y = 32379
B = 3012
The publisher must produce and sell 3012 books.
