Answer 1

Ignore question #1, #2 and #4 I just solved them myself but number 3 is confusing me... Help?

Answer 2

15 days is 1/24th of a year. So, charge 1/24 of the annual rate.

Answer 3

It also confused me???

Answer 4

Ok. How would I do the question? That's what's confusing me. Am I multiplying something to get my answer?

Answer 5

Is interest charged on the amount of the overdrafts as well as the $7.82 fees?

Answer 6

Yes it is the same. Would I take the 12 percent and multiply it by the $7.82?

Answer 7

The answer would be C? Correct?

Answer 8

It's 12% for the whole year. You only have 15 days.
