You invest $275.00 in a money-market account that pays simple interest at a rate of 10%. how long must you leave your investment in the money-market account if you expect to earn $27.50 in interest? a. 0.01 months c. 2 years b. 1 years d. 1 months

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.
