Last season the store had 10 bags of apples for $12.50. What would be the cost of 7 bags at this same rate?

$8.75

Step-by-step explanation: 10/12.50=1.25*7=8.75

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
