You have won the lottery and have been given the choice of receiving $5 million today
or $10 million after 10 years. Assume that the interest rate remains fixed at 10% per
year for the entire 10-year period. You should choose:
A)
$10 million after 10 years, since this is more than you would get if you invested $5
million for 10 years at an annual rate of interest of 10%.
B)
$10 million after 10 years, since that is a larger amount than the present value of $5
million paid after 10 years.
C)
$5 million today, since it would be worth more than $10 million after 10 years if
the $5 million earned interest at the rate of 10% per year.
D)
$10 million after 10 years, since it is the larger amount.
