A primary credit card holder has a current APR of [tex]14.75\%[/tex]. What is the monthly periodic interest rate, rounded to the nearest hundredth of a percent?

A. [tex]12.29\%[/tex]
B. [tex]14.75\%[/tex]
C. [tex]0.01\%[/tex]
D. [tex]1.23\%[/tex]



Answer :

To find the monthly periodic interest rate from an annual percentage rate (APR), you need to divide the APR by the number of months in a year.

1. Given the annual percentage rate (APR) is [tex]\( 14.75\% \)[/tex].

2. To find the monthly periodic interest rate, divide the APR by 12 (since there are 12 months in a year):
[tex]\[ \text{Monthly Periodic Interest Rate} = \frac{APR}{12} = \frac{14.75\%}{12} \][/tex]

3. Perform the division to get the monthly rate:
[tex]\[ \frac{14.75}{12} \approx 1.229167 \% \][/tex]

4. Round the result to the nearest hundredth of a percent. When rounding 1.229167 to the nearest hundredth:
[tex]\[ 1.229167 \approx 1.23 \% \][/tex]

Therefore, the monthly periodic interest rate, rounded to the nearest hundredth of a percent, is [tex]\( 1.23\% \)[/tex].

So, the correct answer is:
[tex]\[ 1.23\% \][/tex]
