Answer:
The correct option is c. 23.53%.
Explanation:
The annual percentage yield (APY) can be calculated using the following formula:
APY = (1 + r / n)^n - 1 .............................. (1)
Where;
APY = Annual percentage yield = ?
r = Annual percentage rate = 22.29%, or 0.2229
n = Number of compounding period per year = Semiannually = 2
Substituting the values into equation (1), we have:
APY = (1 + 0.2229 / 2)^2 - 1
APY = 0.2353211025, or 23.53211025%
Rounding to 2 decimal places, we have:
APY = 23.53%
Therefore, the correct option is c. 23.53%.
