1. Your child has just started college at a private school which currently cost $60,000 per year. He will go to college for 4 years, starting now. You expect tution to increase in cost by 5% per year over the next 3 years.

The college offers you the opportunity to pay $200,000 for all four years regardless of any tuition price increases, but you have to pay the $200,000 today. If your investments earn 9% per year, how much would you save by paying all the tuition today?

2. You own a 10-year-old car and are considering whether to buy a new car now. Your car will last three more years whereupon you will buy a new car. The new car cost $23,000 today and prices on new cars are rising 3% per year on average. Maintenance costs on the old car will average $1000 more than the new car for 3 years starting next year. Your savings account earns 4% compounded annually.

If you buy the car now, how much do you save in present value terms vs. waiting to buy the car?
