The answer would be B, 1,200 yearbooks. Here's why: They need to make at least $12,000 to break even. When doing the math, you won't count the $5 it costs to make the yearbook - as that is more money going out before it comes in. So you would take $12,000 (cost of equipment) divided by $10 (the profit they'd make on each sale of the yearbook) = 1,200.
