Final answer:
To calculate the annual percentage yield (APY) for the savings account with a 2.1% interest rate compounded quarterly, you can use the formula APY = (1 + (interest rate / number of compounding periods)) ^ number of compounding periods - 1. Plugging in the values will give you an APY of 2.13% (rounded to the nearest hundredth of a percent).
Step-by-step explanation:
To calculate the annual percentage yield (APY) for the savings account, you can use the formula:
APY = (1 + (interest rate / number of compounding periods)) ^ number of compounding periods - 1
In this case, the interest rate is 2.1% and the interest is compounded quarterly, so there are 4 compounding periods in a year. Plugging these values into the formula:
APY = (1 + (0.021 / 4)) ^ 4 - 1
Calculating this will give you an APY of 2.13% (rounded to the nearest hundredth of a percent).
