***
compound interest formula: A=P(1+i)^n, P=initial investment, i=interest rate per compounding period, n=number of compounding periods, A=amount after n-periods.
For given problem:
P=$3805
i=.065/52=0.00125
n=40*52=2080 (one score=20 yrs)
A=?
..
A=3805(1+.00125)^2080
A=3805(1.00125)^2080≈51146
The balance in the account after two score years=$51,146
