Hi,
Principal=$650, R=3.5%, T=6 yrs
Amount=Principal * (100+R%/100)^no. of yrs
Amount=650 * (100+3.5/100)^6
Amount= 650 * 103.5/100 * 103.5/100 * 103.5/100 * 103.5/100 * 103.5/100 * 103.5/100<span>
Amount=</span> 650 * 1.035 * 1.035 * 1.035 * 1.035 * 1.035 * <span> 1.035
Amount=799.016</span>
Hope this helps you.
