I took the test and got it right!

$57.61

Step-by-step explanation:

First you want to take the initial deposit and add the 1.32% by multiplying $1435.73 by 1.0132, which should look like this, 1435.73(1.0132), which makes it $1454.68. Next is the tricky part, now you add 1.32% of that new number, 1454.68(1.0132) which equals $1473.88. Then add 1.32% one more time, 1473.88(1.0132) which equals $1493.34. Lastly you subtract the initial deposit from the new number, 1493.34 - 1435.73 which equals $57.61 which is the amount of interest you would gain after 3 years!
