At the end of the summer, I decide to drain the swimming pool. I noticed that it drains
faster when there is more water in the pool. That was interesting to me, so I decided to measure the rate at which it drains. I found that it was draining at a rate of 3% every 5
minutes. How many gallons are left in the pool after 50 minutes? About how many minutes will it take to have less than 1000 gallons in the pool? Justify your answer with a
mathematical model of the problem situation.
