Question

Centerville has a population of 10,000 people. The town is currently experiencing a severe drought. The city council has decided to require all toilets to be fitted with a device that causes it to use 1.5 fewer gallons of water every time the toilet is flushed. An average person flushes a toilet eight times a day. What will be the probable outcome of the town's new policy?

Answer 1

After installing the device, the toilets will use 1.5 fewer gallons per flush.


So each year, the town will save

10,000 (people) * 365 (days in a year) * 8 (flushes per person a day) * 1.5 (gallons per flush saved) 

= 10,000*365*8*1.5= 438,000,000 (gallons a year)


Answer: The town will save about 44 million gallons of water each year
