Question 985541
I need to find a formula to answer an investment increase word problem. I know the interest rate compounded annually and the total amount received. I need to find the original investment amount. 
----------
General Formula:: A(t)=P(1+(r/n))^(nt)
------------------------
Your Problem::
Solve for "P"
P = (A(t))/(1+(r/n))^(nt)
