Compound interest 
20100421 

Kenneth pose la question : Let's say that an investor has $1000.00 to invest for 3 years at a rate of 5% at
compound interest. Here is the formula:
M = 1000(1 + 0.05)^3 = $1157.62
If I want to change 1000(1 + 0.05) to (1000 + 0.05*1000) three times in a
calculation instead of using (1 +0.05)^3, how would this be done?
I cannot get (1000 + 0.05*1000) + (1000 + 0.05*1000) + (1000 + 0.05*1000) to
equal $1157.62.
I know that 1000(1.05)(1.05(1.05) will produce the answer, but I want to try to
use the above nonfactored calculation. Penny Nom lui répond.
