10p-3=2(12+4p)-7

p=10

Step-by-step explanation:

10p - 3 = 2(12+4p) - 7

10p - 3 = 24 +8p-7

10p - 3 = 17 + 8p

Move variable to the left-hand side and change its sign

10p - 8p - 3 = 17  10p - 8p = 17 + 3

2p + 17 +3     2p=20

           p=10

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).
