Answer by Nate(3500) (Show Source): You can put this solution on YOUR website!
the formula i am more used to is this for compound continuously:
y=a(1+r)^t
a=initial amount
y=increased amount
r=rate
t=time
-------------------------------------------------------------------------
y=a(1+r)^t
11000=a(1.09)^2
(11000)/(1.09)^2=a
about $9,258.48
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
A=$11000; r=0.09; t=2; you need to find the Principal or "P"
11000=Pe^(0.09(2))
11000=Pe^0.18
11000=P(1.197)
P=11000/1.19
P=$9187.97
