Step-by-step explanation:

The subject of this question is Mathematics because it involves counting and analyzing different options in a self-service car wash.

There are 4 washing stalls in the car wash and each customer can choose from 3 options: 1) rinse only, 2) wash and rinse, and 3) wash, rinse, and wax.
