John earns $8 per hour for his after-school job. He never works more than 18 hours in a week, and he never works a fraction of an hour. The equation that models this situation is A=8h, where A represents the amount John earns and h represents the number of hours John works in a week. What is the reasonable domain of the function A in the given context?

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
