Question:
The U.S. Consumer Price Index for the years 1990–2013 is approximated by A(t) = 100e0.0264t, where t represents the number of years after 1990. (Since A(16) is about 153, the amount of goods that could be purchased for $100 in 1990 cost about $153 in 2006.) Use the function to determine the year in which costs will be 125% higher than in 1990.
