Answer:

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.
