The formula that I was given is: 1020 sqrt P (1-.01 sqrt P)=G. If P is the population in thousands, this formula is the amount of water in gallons per minute the city needs.

Question: A city had a population of 43,250 people five years ago. Since then the population increased by 2,250 people. How many more gallons per minute had to be added to the city’s pumping capacity?

Question: A city has about 37,550 people. How many gallons per minute must the city’s pumps be able to supply?
