The personnel costs in the city of Greenberg were $9,500,000 in 2009. In the recent past the personnel costs have increased at the rate of 4.2% annually. To model this, the city manager uses the function C(t) = 9.5(1.042)' where C(t) is the annual personnel costs,in millions of dollars, t years past 2009 1) write the equation that can be solved to find in what year the personnel costs will be double the 2009 personnel costs. Then 2) solve the equation numerically (use the Table feature of your calculator) or graphically and determine the year.
