At a little-known vacation spot, taxi fares are a bargain. a 14-mile taxi ride takes 16 minutes and costs $11.20. you want to find the cost of a 42-minute taxi ride. what unit price do you need?

the aswere is the one with all 8's and the second one is with the 10,8 and 6

step-by-step explanation:

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).

i believe a. 12x≥120 is the answer
