Answer:
The value of her investment will be $7,801.36 after 6 years.
Step-by-step explanation:
We are given the following in the question:
P = $6400
r = 3.3% = 0.033
t = 6 years
Formula for compound interest:
[tex]A = pe^{rt}[/tex]
where A is the amount, p is the principal, r is the interest rate, t is the time in years when compounded continuously .
Putting values, we get,
[tex]A = 6400e^{6\times 0.033}\\A = \$7,801.36[/tex]
Thus, the value of her investment will be $7,801.36 after 6 years.
