Suppose that the annual rate of inflation averages $4 \%$ over the next 10 years. With this rate of inflation, the approximate cost $C$ of goods or services during any year in that decade will be given by $C(t)=P(1.04)^{r}, \quad 0 \leq t \leq 10$
where $t$ is time in years and $P$ is the present cost. If the price of an oil change for your car is presently $\$ 24.95$, estimate the price 10 years from now.
