I need help with a couple questions if you could help ASAP that would be nice thank you!

$22. if larry's profit were to minimize by one for every hour his store were to be closed, we would subtract 30 by 8.

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.
