Question

New US regulations require toilets use no more than 1.6 gallons per flush. Prior regulations allowed 3.4 gallons per flush. Find the number of gallons of water saved in one year if a family flushes an average of 21 times per day.

Answer 1

13, 797 galloons

Explanation:

(21x3.4) - (21x1.6)

71.4 - 33.6 = 37.8 gallons saved per day

37.8 x 365 = 13, 797
