The investment decision primarily affects which part of a business?

On his 20th birthday, a man makes a resolution. He will put $30 cash under his bed at the end of every month starting from today. His birthday today is the first day of the month. So the first addition to his cash stash will be in one month. He will write in his will that when he dies the cash under the bed should be given to charity. If the man lives for another 60 years, how much money will be under his bed if he dies just after making his last (720th) addition? Also, what will be the real value of that cash in today's prices if inflation is expected to 2.5% pa? Assume that the inflation rate is an effective annual rate and is not expected to change. The answers are given in the same order, the amount of money under his bed in 60 years, and the real value of that money in today's prices. An equity index is currently at 5,000 points.

For an asset's price to double from say $1 to$2 in one year, what must its effective annual return be? Note that an effective annual return is also called a net discrete return per annum. If the price now is $P_0$ and the price in one year is $P_1$ then the effective annul return over the next year is:

$$r_\text{effective annual} = \dfrac{P_1 - P_0}{P_0} = \text{NDR}_\text{annual}$$
