Given:
Principal amount -1000
Interest =6.5 %
Time = 3 years.
The compound interest formula is
[tex]A=P(1+r)^t[/tex]Substitute P=1000, r=6.5/100 and t=3, we get
[tex]A=1000(1+\frac{6.5}{100})^3[/tex][tex]A=1000(1+0.065)^3[/tex][tex]A=1000(1.065)^3[/tex][tex]A=1207.9496[/tex]The amount in the account at the end of three years is $ 1207.95.
