Answer:

$326.94

Explanation:

For this equation you are going to do a exponential function, since we are working with percents. To do this you will make the equation

(starting price)x(1-percent)^(t) t=years

which will create the equation

800(0.88)^t

You will then plug in t=7

800(0.88)^7 =

800(0.409) =

326.94 (you will cut it off at the hundredth position because it is working with money)
