On a treasure map, the route is 3 inches north, 2 inches west, 1. 5 inches north, and 0. 25 inches east. The actual distance of the entire route is 135 feet. What does each inch on the map represent? Explain how you found the answer.

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).

the answer is z7+8/5
