#### Explanation:

This is basically a line (linear equation) where the fixed expense is the intercept and the variable sales are the slope. With such an equation, any projection of profit for any number of shirts can be calculated. Given a particular profit, the equation can be rearranged to find the number of shirts that must be sold.

$P r o f i t = S h i r t s \cdot P r i c e - E x p e n s e s$

71 = Shirts * 4 – 25# ; $71 + 25 = S h i r t s \cdot 4$ ; $96 = S h i r t s \cdot 4$

$S h i r t s = \left(\frac{96}{4}\right) = 24$
