If susan had no previous balance on her credit card, and she manages to pay off the balance within 1 month, how much will she have to pay in interest?

She will pay $5.33 in interest.

Explanation:

200 dollars at a 32% interest rates means that the interest accrued for the full year will be:

200*0.32 = 64 dollars

Since she is managing to pay her balance within one month, she will only be charged for that month, hence her interest payment will be:

64/12 = 5.33 dollars

i believe the answer would be 'd'.

hope this !
