Maggie is considering two investments. Investment A Investment B Principal $10,000 $8,000 Interest rate 3% 2.8% Time in years 5
lana [24]
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= \frac{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= \frac{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.
