A family of five recently replaced its 5-gallon-per minute showerheads with water-saving 2-gallon per minute showerheads. Each member of the family averages 8 minutes in the shower per day. In a 30-day period, how many few gallons of water will the family use with the new showerheads?

1. 60

2. 800

3. 2400

4. 3600

5. 7200

2400 gallons of water

Step-by-step explanation:

The new shower head releases 2 gallons per minute as compared to the old type.

each person spends an average of 8 minutes in shower per day. This means each person will use 8*2 number of gallons per day.

the number of persons in the family is 5.

if 1 person uses 8*2 gallons per day, 5 people will require 8*2*5

In a 30 days period the number of gallons used by the family will be

=8*2*5*30

=2400 gallons.
