principal rate time coumpounded interest
------------------------------------------------------------------------------
A(t) = P(1 + (r/n))^(nt)
---------------------------------
$6000 6.25% 3 years annually __________
A(3) = 6000(1+(0.0625/1))^(1*3)
-----
A(3) = 6000(1.0625)^3
-----
A(3) = 6000*1.1995
A(3) = $7196.78
======================================================
$300 5% 2 years semiannualy _______________
A(2) = 300(1+(0.05/1))^(1*2)
A(2) = 300(1.05)^2
A(2) = $330.75

A=P%2A%281%2Bi%29%5En for compounded annually and
A=P%2A%281%2Bi%2F2%29%5E%282n%29 compounded semi-annually where i is interest and n the number of years
$6000, 6.25% ,3 years annually
A%28t%29+=%246000%281%2B0.0625%29%5E3=7196.78
$300, 5%, 2 years semi-annually
A%28t%29+=%24300%281%2B0.05%2F2%29%5E%282%2A2%29=331.14
