Ichiro took out a subsidized student loan of $13,000 at a 3.6% apr,
compounded monthly, to pay for his last two semesters of college. if he will
begin paying off the loan in 15 months, how much will he owe when he
begins making payments?

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.
