Final answer:
The subject of this question is Mathematics. The question involves evaluating future prices of a certain item using an exponential function.
Step-by-step explanation:
The subject of this question is Mathematics. The question involves evaluating future prices of a certain item using an exponential function.
The function, P_t = 1500 × 1.056^t, represents the future price in dollars (P_t) given the number of years from today (t). The base of the exponential function, 1.056, represents the growth rate of the item's price.
For example, if t = 1, the future price (P_t) would be 1500 × 1.056^1 = 1584 dollars. If t = 2, the future price would be 1500 × 1.056^2 = 1677.86 dollars.
