To solve this we are going to use the simple interest formula:
A=P(a+rt)
where

A is the final amount.

P is the initial investment.

r is the interest rate in decimal form.

t is the time in years.

Investment A. We know that the initial investment is $10,000, so
P=10000. We also know that the number of years is 5, so
t=5. To convert the interest rate to decimal form, we are going to divide the rate by 100%

r= (3)/(100) =0.03
Lets replace those values in our formula to find
A:

A=P(a+rt)

A=10000(1+0.03*5)

A=11500

Investment B.
P=8000,
t=15, and
r= (2.8)/(100) =0.028.

A=P(a+rt)

A=8000(1+0.028*15)

A=11360

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