Answer: $21
Explanation: The Annual Percentage Rate is 18%, therefore the percentage rate for one month is:
0.18/12 = 0.015 = 1.5%
To get the total finance charge, we first calculate the monthly percentage on $600 thus:
600 X 0.015 = $9
Now we calculate the cash advance fee using 2% thus:
600 X 0.02 = $12
Total finance charge = $9 + $12 = $21.
