5(x-6)+ 3x = 3/4(2x-8)

x = 3.69 (3 significant figures)

Step-by-step explanation:

5(x - 6) + 3x = 3/4(2x - 8)

5x - 30 + 3x = 1.5x - 6

5x + 3x - 1.5x = 30 - 6

6.5x = 24

x = 3.6923 (5 significant figures)

x = 3.69 (3 significant figures)

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).
