You place $1,500 in a savings account earning 3% interest compounded annually. How much will you have at the end of four years? How much would you have at the end of four years if interest is compounded semiannually?
The semi-annual answer given by Anonymous is correct
For the annual compounding, we have
1500(1.03)^4 = $ 1688.26
Compounded annually: $1680
Semi-annually $1689.74
A=P(1+rt)
