Answer:
a. True
Explanation:
A periodic interest rate can be defined as an interest rate that is realizable on an investment such as securities (bonds) or charged on a loan over a specific period of time.
Mathematically, it is given by the formula;
[tex] Periodic \; interest \; rate = \frac {annual \; interest \; rate}{number \; of \; compounding \; periods} [/tex]
Hence, if we are given a periodic interest rate, say a monthly rate, we can find the nominal annual rate by multiplying the periodic rate by the number of periods per year.
