A computer is purchased for $3200. Its value each year is about 79% of the value the preceding year. Its value, in dollars, after t years is given by the exponential function
%22V%28t%29%22=+3200%280.79%29%5Et
Find the value of the computer after 2 years.

Everywhere you see a t, put a 2

%22V%28t%29%22=+3200%280.79%29%5Et
%22V%282%29%22=+3200%280.79%29%5E2

Now get a calculator and punch out the right side,
and leave the left side just as it is:

%22V%282%29%22=1997.12

Put a dollar mark :

%22V%282%29%22=%22%241997.12%22
