Question 6676: 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 2250 people. How many more gallons per minute had to be added to the city's pumping capacity?

To solve this problem, you need to substitute P=2250 (as P= 2.25 thousands) into the equation and grind away.
G+=+1020sqrt%28P%29%281-.01sqrt%28P%29%29
G+=+1020sqrt%282.25%29%281-.01sqrt%282.25%29%29
G+=+1020%281.5%29%281-.01%281.5%29%29
G+=+%281530%29%280.985%29
G+=+1507.05 Gallons per minute.
