Question 326537
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 
{{{"V(t)"= 3200(0.79)^t}}}
Find the value of the computer after 2 years.

<pre><b>
Everywhere you see a {{{t}}}, put a {{{2}}}

{{{"V(t)"= 3200(0.79)^t}}}
{{{"V(2)"= 3200(0.79)^2}}}

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

{{{"V(2)"=1997.12}}}

Put a dollar mark :

{{{"V(2)"="$1997.12"}}}
