What do you add to 5 3/8 to make 9

3 and 5/8

Step-by-step explanation:

9 - 5 3/8 = 3 and 5/8

29/8

Step-by-step explanation:

First Make It into a proper fraction

5 3/8

5/1+ 3/8

8/5*5/1+3/8

40/8+ 3/8

Now you subtract from 9:

9- 43/8

9/1-43/8

8/8*9/1-43/8

72/8-43/8

and that equals 29/8

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).
