Problem

Evaluating an exponential function that models a real-worid situation If the rate of inflation is $2.5 \%$ per year, the future price $p(t)$ (in dollars) of a certain item can be modeled by the following exponential function, where $f$ is the number of years from today. \[ p(t)=1200(1.025)^{t} \] Find the current price of the item and the price 8 years from today. Round your answers to the nearest dollar as necessary. Current price: Price 8 years from today: $5 \square$ Explanation Check Terms of Use Privery center Accessionity

Solution

Step 1 :The question is asking for the current price of the item and the price 8 years from today. The current price can be found by substituting t=0 in the given function, because the current time is 0 years from today. The price 8 years from today can be found by substituting t=8 in the given function.

Step 2 :Let's calculate the current price: \(p(0)=1200(1.025)^{0}\)

Step 3 :So, the current price of the item is \(\boxed{1200}\) dollars

Step 4 :Now, let's calculate the price 8 years from today: \(p(8)=1200(1.025)^{8}\)

Step 5 :So, the price 8 years from today will be \(\boxed{1462}\) dollars

Step 6 :Final Answer: The current price of the item is \(\boxed{1200}\) dollars and the price 8 years from today will be \(\boxed{1462}\) dollars.
