Fleta has $100.00 in a savings account that earns 5% interest
per year. The interest is not compounded.
What is the total amount Fleta will have in 3 years?

First year 100x0.05 = 5
Second year 100x0.05 = 5
Third year 100x0.05 = 5
Total interest 15$ for three year + the original amount mean 100
Total after three year
$115

Because the interest not compounded mean : where previously accumulated interest is not added to the principal amount of the current period, so there is no compounding.
