Answer: Andrew
Given:
<span>$750- Andrew’s mutual fund every year
until the 10th year</span>
<span>$9000 – Stephanie’s mutual fund in the
10th year</span>
5%- average percent rate of return
To determine who will have the larger
mutual fund balance in 20 years, we will use the simple interest formula which
is the interest gained only on the principal.
Let X= the principal amount of Andrew’s
mutual fund after 20 years
X=(750+750(.05))*20
X =(750+37.50)*20
X=787.50(20)
X=15,750 in 20 years
<span>Let Y=principal amount of Stepanie’s mutual
fund after another 10th year</span>
Y=9000+(9000(.05)*10)
Y=9000+(450*10)
Y=9000+4500
Y=13,500
<span>X>Y so
Andrew has the greater mutual balance. </span>
