Question

There are already 1,200 gallons of water in a swimming pool. If water is filling the pool at a rate of 30 gallons per minute, which expression indicates the amount of water, in gallons, in the swimming pool after m minutes?

Answer 1

n = 30m + 1,200

Explanation:

let n = gallons

m = minutes

There are 30 gallons per minute, so 30 is multiplied by the minutes, and because there are already 1,200 gallons of water, you add 1,200
