A=P(1+(r/n))nt
Where A will be the total amount due
P is the Principal
r is the rate in decimal form
n is the number of times compounded annually
t is the years
P=2000
r=.05
n=12 (because compounding monthly is 12 times per year)
t=3
Plug all that into the equation
A=2000(1+(.05/12))(12)(3)
A= $2322.94
