1) Since January 1980, the population of the city of Brownville has grown according to the mathematical model y = 720,500(1.022), where x is the number of years since January 1980.
a) Explain what the numbers 720,500 and 1.022 represent in this model.
b) What would the population be in 2000 if the growth continues at the same rate.
c) Use this model to predict about when the population of Brownville will first reach 1,000,000.
