In a bank account, a paid-out expense is

called a debit, and a deposit is called a credit.

would you use positive or negative integers to

represent credits? debits? explain.

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.
