Answer:
The answer is (B) $1,307
Step-by-step explanation:
First you would plug the $5000, 5 Years and 8% Interest(Compound) into your Formula - A=P(1+r)t
A=5000(1+.08)5
Which the interest is $2346.64
<u>__ _________________________________________________</u>
Next you would plug $5000, 3 Years and 6.5% Interest(Compound) Into your Formula - A=P(1=r)t
A=5000(1+.065)3
Which the future value is $1039.75
<u>__ _________________________________________________</u>
Finally you would subtract $2346.64 by $1039.75 and then round the difference to the nearest dollar.
