Answer:
4152 books
Step-by-step explanation:
As we will see when we write the equations, the number of books will be the difference in fixed costs divided by the difference in variable costs:
(66755 -23159)/(23 -12.50) = 43596/10.5 = 4152
The costs of the two methods are the same for production of 4152 books.
__
The costs for method 1 for production of b books are ...
m1 = 66755 +12.50b
The costs for method 2 for production of b books are ...
m2 = 23159 +23b
The two costs are equal when ...
m2 = m1
23159 +23b = 66755 +12.50b
10.5b = 43596 . . . . . . . . . . . subtract 12.50b+23159 from both sides
b = 43596/10.5 . . . . divide by the coefficient of b
b = 4152 . . . . . . . . . book production to make the costs the same
For 4152 books produced, the costs from the two methods will be the same.
