A = final amount
P = Principal, the sum of money originally invested
r = rate, the interest rate
n = number of compounding periods, in your problem this is 2
t = time, the number of years, in your problem 100
``````````````````````````````````````````````````````````````
A = P(1+r/n)^nt
1,000,000 = P(1+0.10/2)^2*100
1,000,000 = P(1.05)^200
1,000,000 = P*17,292.58 divide both sides by 17,292.58
P = 1.000.000/17.292.58 = 57.83
This problem is to teach you the power of compounding.
