dI/dt = 3.087e^0.0384t

dollars per year, where C is the consumer price index and t is the number of years past 1990.

(a) Does the model for the rate reflect the fact that the Social Security Administration's data (actual and projected for selected years from 1995 to 2070) in the table show that the CPI is increasing? Explain.
