You can put this solution on YOUR website! How much money will you have after 4 years if you invest $2000 at an annual rate of 5% compounded semiannually
---------------
A(t) = P(1+(r/n))^(nt)
------
A(4) = 2000(1+(0.05/2))^(2*4)
-------------------------------
A(4) = 2000*1.2184
---
A(4) = $2436.81
