David opens a savings account with a 7.5% annual interest rate. Which choice best represents his monthly interest rate? A. 6.25%
B. 6.04%
C. 0.625%
D. 0.604%

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.

Its 35 i think if the answer is incorrect i apologize
