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 the following exponential function, where t is the number of years from today. p(t) = 1200(1.028)t

find the current price of the item and the price 9 years from today. Round your answers to the nearest dollar as necessary.
Current price: _$
Price 9 years from today: _$
