Question
If the rate of inflation is \( 2.8 \% \) per year, the future price \( p(t) \) (in dollars) of a certain item can be modeled by \( t \) exponential function, where \( t \) is the number of years from today. \[ p(t)=3000(1.028)^{t} \] 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: 8 years from today: \( \$ \square \)

The current price of the item, as given in the exponential function, is simply \( \$3000 \). To find the price 8 years from today, we'll plug \( t = 8 \) into the equation: \[ p(8) = 3000(1.028)^{8} \] Calculating this gives: \[ p(8) = 3000 \times (1.28) = 3000 \times 1.239 \approx 3717 \] Thus, rounding to the nearest dollar, the price 8 years from today will be approximately \( \$3717 \). Current price: \( \$3000 \) 8 years from today: \( \$3717 \)
