3 Gurgling Springs, Inc is a bottler of natural spring water distributed throughout the New England states Five-gallon containers of GSI spring water are regionally promoted and distributed through grocery chains Operating experience during the past year suggests the following demand function for its spring water:

Q = 450 – 100P + 00001Pop + 0005Y + 0003A

where: Q = quantity in thousands of containers,

P = Price ($) = $4

Pop = Population (# of people) = 4,000,000

Y = Disposable Income per capita ($) = $50,000

A = Advertising expenditures ($) = 400,000

a Determine the demandcurve faced by GSI

b What is theinverse demand curve faced by GSI? (note: simplify—no fractions)
