There was a big sale on cat food at the pet store. 20 people bought cat food that day. The first 8 customers bought 3 cases each. The next four customers bought 2 cases each. The last 8 customers of the day only bought 1 case each. How many cases of cat food were sold?

The first 8 customers bought 8 * 3 = 24 cases. The next 4 customers bought 4 * 2 = 8 cases. The last 8 customers bought 8 * 1 = 8. In total 24 + 8 + 8 = 40 cases were sold.
Thus, the answer is 40.
