Answer: The answer is given below
Explanation:
a. What is the true monthly rate of interest?
The monthly rate of interest will be the annual percentage rate of charge given in the question divided by the number of months. This will be:
= APR/12
= 6.5%/12
= 0.065/12
= 0.0054
= 0.54%
b. What is the EAR?
The effective annual rate will be calculated using the formula:
EAR = (1 + (APR / m)^ m) - 1
EAR = (1 + (0.065/ 12)^12) - 1
EAR = [(1 + 0.0054)^12] - 1
EAR = (1.0054)^12 - 1
EAR = 1.06676 - 1
EAR = 0.06676
EAR = 6.68%
