My question is
2. Our family has a small pool for relaxing in the summer that holds 1500 gallons of water.
I decided to fill the pool for the summer. When I had 5 gallons of water in the pool, I
decided that I didn’t want to stand outside and watch the pool fill, so I wanted to figure
out how long it would take so that I could leave, but come back to turn off the water at
the right time. I checked the flow on the hose and found that it was filling the pool at a
rate of 2 gallons every 5 minutes. How many gallons of water will be in the pool after
50 minutes? How many minutes will it take to fill the pool? Justify your answer with a mathematical model of the problem situation.
Is the answer 2(n-1) + 5?
