If a certain city is losing 12 percent of its daily water supply each day because of water-main breaks, what is the dollar cost to the city per day for this loss?
(1) The city’s daily water supply is 350 million gallons.
(2) The cost to the city for each 12,000 gallons of water lost is $2.
Kudos for a correct solution.Need to find the cost for 12% of the water loss
1: Insufficient - WE can find the amount of water loss but not cost
2: In sufficient - Cost of gallon of water can be calculated but not the loss of water
combining both we can find the total cost for lost water
