Suppose you deposit $200 today into a bank account with a variable interest rate and will receive a payment in one year. True or False: If during the year the interest rate rises, this increases the future value of your investment.

Suppose you win a small lottery and have the choice of two ways to be paid: You can accept the money in a lump sum or in a series of payments over time. If you pick the lump sum, you get $2,800 today. If you pick payments over time, you get three payments: $1,000 today, $1,000 1 year from today, and $1,000 2 years from today. At an interest rate of 9% per year, the winner would be better off accepting the ----- , since it has the greater present value.
