Compound interest 2010-04-21
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 non-factored calculation.

Choosing an investment 2004-06-09
Max pose la question :
Let's say I have a list of different possible investements, and the list shows me my cost, and how much each investment will sell for.

In order to compare the investments and put them in order of relative profitability, I would want to sort them by their profits as percentages of what? Also, if each investment had an equal probability

of losing exactly 10% of the sell price before I sold would that have any relevance to the way I would calculate it?
