What is 1 1/2 subtracted from the sum of 4 2/3 and 5 2/5
​

8 17/30

Step-by-step explanation:

Add 4 2/3 + 5 2/5 = 10 1/15

10 1/15 - 1 1/2

= 8 17/30

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).

15.36 per mile

but forgot to round

i am pretty sure
