Answer to Question 2
To compare between the two investments, it is necessary to calculate the required principal to be deposited in the bank at 9 rate of interest for ten years to generate 12,990.
The present value of 12,990 at 9 rate of interest is 12,990/(1.09 )10 = 5,487.12.
Hence, if the rate of interest is 9, the sum of 12,990 can be earned by depositing approximately 5,488 in the bank for ten years.
Because George needs to invest a smaller amount of money to generate the same return from the bank, investing in the bank is a better option for him.
