Lacy bought her friend a pair of shoes for her birthday. The box is 13 inches wide, 6 inches long, and 5 inches tall. Mark bought the same friend a book that measures 7 inches long, 4 inches wide, and 2 inches high. If they both wrap their gifts, how much more wrapping paper will Lacy use than Mark?

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
