Question

A small swimming pool initially contains 400 gallons of water, and water is being added at a rate of 10 gallons per minute. Which expression represents the volume of the pool after minutes?

-10t + 400
10t + 400
400t + 10
400(1.1)^t

Answer 1

Answer:

10t + 400 would be the answer.

Step-by-step explanation:

every hour, there would be 10 gallons added to the pool, so time should be the letter "t" in the equation.

Also, there's already 400 gallons of water existing in the pool, so we need to add 400 gallons.

Therefore, 10t + 400 would be the answer.
