Metro city planners proposes that a community conserve its water supply by replacing all the community’s toilets with low-flush models that use only 2 liters per flush. assume that there is about 1 toilet for every 3 persons, that existing toilets use an average of 15 liters per flush, that a toilet is flushed on average 14 times per day, and that the cost to install each new toilet is $150. write a program that would estimate the magnitude (liters/day) and cost of the water saved based on the community’s population.
