Alonzo rented a truck for one day. There was a base fee of $16.95, and there was an additional charge of 94 cents for each mile driven. Alonzo had to pay $201.19 when he returned the truck. For how many miles did he drive the truck?

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).
