Identical copies of books are being packaged and shipped to a bookstore. There are 18 boxes of books that each weigh 31 pounds. The boxes have space for some more books to be added; however, the total weight of all of the boxes cannot exceed 615 pounds. Two workers, Kevin and Olivia. want to determine how many more pounds of books they can add into each box without going over the weight limit. Kevin wrote the inequality 18(x +31) 615.

Olivia wrote the inequality 18(x +31) s 615.

Who wrote the correct inequality? How many extra pounds can they add to each box?

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).
