Answer:
Option B is correct.
Explanation:
We are given that $20,000 for 14 years compounded at 10% semiannually.
We need to find how many periods are there?
Semiannually means twice a year
Which means that the amount is compounded twice in one year.
So, for 14 years: 14*2 = 28
So, 28 periods is the correct answer.
Option B is correct.
