Answer:
5.03%
Explanation:
In order to compute the effective annual rate on the commercial paper,we need to first of all establish the interest rate in the six-month instrument
interest=($500,000-$488,000)/$488,000=2.46%
Effective annual rate=(1+2.46% /6)^12-1
By dividing by six, we are reducing the rate to monthly terms
By raising to the power of 12 we are converting from a monthly rate to yearly rate
Effective annual rate=5.03%
