SOLUTION:
Step 1:
In this question, we have the following:
Step 2:
Using the sample solution in the second picture, we can see that the
The Formula of the Effective Interest Rate is given by:
In this case, the Effective Interest Rate, E = 0.05083001 %
Step 3:
Then, the detailed solution is as follows:
In this case, the Effective Interest Rate, E = 0. 05042
Step 4:
One more part which investment is the better one?
Despite the two values are:
But for the semi-annual investment, E= 0.05083001 %
and the quarterly investment, E = 0.05042%
CONCLUSION:
The better investment is that of the semi-annual investment because it is bigger than the quarterly investment.
