Answer:

  • Tower #1: 1550 gallons
  • Tower #2: 670 gallons

Step-by-step explanation:

After 5 minutes, the amount of water that has flowed is ...

  (20 gal/min)(5 min) = 100 gal

That amount has flowed out of Tower #1, so it now has ...

  1650 -100 = 1550 . . . gallons in Tower #1

That amount has flowed into Tower #2, so it now has ...

  570 +100 = 670 . . . gallons in Tower #2
