The amount of money in the account in 40 years is $28, 196
Equation:
I = Prt
First, converting R percent to r a decimal
r = R/100 = 10.8%/100 = 0.108 per year,
then, solving our equation
I = 5300 × 0.108 × 20 = 11448
I = $ 11,448.00
Therefore, this is the interest gained after 20 years.
To get the interest for an additional 20 years, we would multiply by 2
11,448 * 2
= $ 22,896.00
Therefore, the total money gained after this period would be:
$22,896 + $5,300
= $28, 196
