] Sandy works at a clothing store. She makes $7 per hour plus earns 10% commission on her sales. She worked 76 hours over the last two weeks and had a total of $2,454 in sales before taxes.

Which of the following is closest to how much she will earn in hourly wages and commission for those two weeks?

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).

it would be 4 over -2 divided by -1 over 3.

if you want a solution it would be 4

you flip it so it would be 4/-2 divided by 3/-1 then it would be 12/3 and you would simplify it to 4
