Answer: 9000

Given:

10 automatic sprinkler activated 10 minutes for 2 sessions daily.

Each sprinkler provides 1.5 gallons of water per minute

Question:

How many gallons of water is the neighbor using during a 30-day billing cycle?

Solution:

Each sprinkler provides water (10*2) or 20 minutes daily. In 20 minutes each sprinkler can provide (20*1.5) or 30 gallons of water. There are 10 sprinklers so (10*30) 300 gallons all in all daily. In 30 days, (30*300)9000 gallons of water are consumed.
