Aquarium one contains 4.6 gallons of water. Louise will begin filling aquarium one at a rate of 1.2 gallons per minute.

Aquarium two contains 54.6 gallons of water. Isaac will begin draining aquarium to at a rate of 0.8 gallons per minute.

After how many minutes will both aquariums contain the same amount of water?

25

Step-by-step explanation:

4.6 + 1.2g = 54.6 -.8g

1.2g + .8g = 54.6 - 4.6

2g = 50

g = 25

i think the answer would be c

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).
