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)
