Answer:
B. 1.67%
Step-by-step explanation:
The periodic rate is the annual interest rate divided by the number of periods.
Therefore, we divide the annual interest rate by 12.
[tex]20\% \div 12 =1.67\% $(correct to two decimal places)[/tex]
Therefore, the periodic interest rate for Jack's credit card from June 3
to July 2 is 1.67%.
