Question

Someone please help me

Answer 1

Set up the methods to equal each other:


`47,085 + 11.25x = 19,577 + 24.25x`

The numbers will represent the one-time fixed costs, and the numbers with variables will represent variable costs.

Subtract 19,577 from both sides:


`27508 + 11.25x = 24.25x`

Subtract 11.25x from both sides:


`27508 = 13x`

Divide both sides by 13 to get x by itself:


`x = 2116`

The two methods will cost the same if 2116 books are produced.
