Toilets

A federal law requires that all residential toilets sold in the United States use no more than 1 3/5 gallons of water per flush. Prior to this legislation, conventional toilets used 3 2/5 gallons of water per flush. Find the amount of water saved in one year by a family flushing the toilet 22 times each day if one conventional toilet is replaced with a new low flow one. (1 year = 365 days)

Result
