Answer:
if you want to maximize the amount of interest that you will earn, then you should choose bank C
Explanation:
interest gained in 1 year in bank A = $5,600 x 4.61% = $258.16
interest gained in 1 year in bank B = $5,600 x [(1 + 4.15%/12)¹² - 1] = $236.87
interest gained in 1 year in bank C = $5,600 x [(1 + 4.57%/2)² - 1] = $258.84
interest gained in 1 year in bank D = $5,600 x [(1 + 4.25%/4)⁴ - 1] = $241.82
we have to calculate the effective interest rate paid by each bank using the following formula:
effective interest = (1 + i/n)ⁿ - 1
