after the end of an advertising campaign is given by S(t) = 9 - 10e^-0.3t. What is the average
number of cheeseburgers sold each day during the first 7 days after the end of the
advertising campaign?

Here is the answer to the integration

(9 - 10/e^(0.3*t))*x

Now just solve it from o to 7

I think the integration is supposed to be

9 t+ 33.33*e^(-0.3*t)
