Answer to Question 1

This policy has an internal rate of return of 1/20 = 5. If the interest rate exceeds 5, then there are better investments elsewhere. If the interest rate is less than 5, this is a good deal.

Answer to Question 2

One is indifferent when the future stream of tuition payments has a present value of 38,000.

20,000  1 + 1/(1 + irr) = 38,000
1/(1 + irr) = 0.9 or irr = 11.11

If the interest rate is 11.11, the student can pay the first year's tuition and deposit 18,000 in a bank account today and withdraw 20,000 at the end of the first year to make her second payment. If the interest rate exceeds 11.11, the student can deposit 18,000 today, make the 20,000 payment in Year 2, and still have something left over. If the interest rate is less than 11.11, the student is better paying the 38,000 all at once.
