Suppose the current, zero-coupon, yield curve for risk-free bonds is as follows:

Maturity (years)	1	2	3	4	5
Yield to Maturity	4.22%	4.55%	4.69%	5.08%	5.30%

a. What is the price per $100 face value of a 3-year, zero-coupon risk-free bond?

b. What is the price per $100 face value of a 4-year, zero-coupon, risk-free bond?

c. What is the risk-free interest rate for a 1-year maturity?

Note: Assume annual compounding.
