Rudy and Ritchie Ling ran a camp this summer for children in their neighborhood. Rudy spent $135 on supplies and earned $250 before expenses. Ritchie spent $140 on supplies and made $210 before expenses. What is the combined revenue for the two brothers

the answer should be a. snail

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).

your answer is b.

x = 33.9

y = 65.6
