Answer:
9 different car washes
Explanation:
From the services that Jorge offers we can see that there are 3 options (wax, vacuum, and interior cleanings) on 3 different categories of vehicles (cars, trucks, and SUV). Therefore, in order to calculate the number of possible combinations or car washes that you can make, we need to multiply the number of options by the number of categories of vehicles. Like so...
3 * 3 = 9
Therefore, we can see that there are a total of 9 different car washes that you can make for the weekend.
