Point R is on line segment \overline{QS} QS . Given QS=2x+2,QS=2x+2, QR=3x-5,QR=3x−5, and RS=5x-5,RS=5x−5, determine the numerical length of \overline{QR}. QR .

the correct answer is 5 6 and 7

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).
