Answer:
$5,211.30
Explanation:
We have to calculate compound interest with the formula

Where A = Amount after maturity
P = Principal amount ( $4,000)
r = Rate of interest 13.3% in decimal ( 0.133)
n = number of compounding period, monthly ( 12 )
t = Time in years ( 2 )
Now we put the values in the formula




A = $5,211.30
After 2 years investment would be $5,211.30.
