Ons A swimming pool has 411 gallons of water in it and is leaking. The change in the amount of water is - 13
gallons per hour. How many gallons of water will the pool contain after 3 hours?

372 gallons

Step-by-step explanation:

The original amount of water in the pool is 411 gallons

The loss is 13 gallons

1 hour = -13 gallons

3 hours = (3 x -13) = -39 gallons

The question asks, how much water will the pool contain after 3 hours?

We already know that the pool will have lost 39 gallons so the answer will be gotten from subtracting 39 gallons from the original amount (411 gallons)

411 - 39 = 372
