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?   Question 4 options: The town will save about 44 million gallons of water each year The town will lose about 15,000 gallons of water each month The town will save about 15,000 gallons of water each month The town will lose around 44 million gallons of water each week

Answer 1

Answer is "They save 44 million gallons of water every year"

Explanation - If all 10,000 people in the town flush the water-saving toilet eight times a day, they will save 120,000 gallons in a day. If the savings is multiplied by 365—the number of days in a year—they will save 43.8 million gallons each year.

Answer 2

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
