To solve this we are going to use the simple interest formula:

where

is the final amount.

is the initial investment.

is the interest rate in decimal form.

is the time in years.
Investment A. We know that the initial investment is $10,000, so

. We also know that the number of years is 5, so

. To convert the interest rate to decimal form, we are going to divide the rate by 100%

Lets replace those values in our formula to find

:


Investment B. 
,

, and

.



We can conclude that
investment A will be worth than investment B at the end of the investment period.
