If the annual rate of inflation averages $ 4\% $ over the next $ 10 $ years, the approximate costs $ C $ of goods or services during any year in that decade will be modeled by $ C(t) = P(1.04)^t $, where $ t $ is the time in years and $ P $ is the present cost. The price of an oil change for your car is presently $ \$23.95 $. Estimate the price $ 10 $ years from now.

Key Concepts

Exponential Growth

Exponential growth refers to the process where a quantity increases by a constant percentage over equal time periods. In financial and economic contexts, this means that even small increases can lead to significant growth over time because each new increase is based on a progressively larger amount.

Inflation Modeling

Inflation modeling involves using mathematical techniques to predict how the general price level of goods and services will change over time. With a constant annual inflation rate, this change is typically modeled using an exponential function, reflecting the compounded effect of inflation year after year.

Future Value Estimation

Future value estimation is the process of calculating what an amount of money today will be worth at a future date given a certain rate of increase. In the context of inflation, it helps estimate how much it will cost for goods or services in the future, using a formula that treats the current price as the present value and applies exponential growth over time.
