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 5-year, zero-coupon, risk-free bond? c. What is the risk-free interest rate for a 4-year maturity? Note: Assume annual compounding. a. What is the price per $100 face value of a 3-year, zero-coupon risk-free bond? The price is $ (Round to the nearest cent.) b. What is the price per $100 face value of a 5-year, zero-coupon, risk-free bond? The price is $11. (Round to the nearest cent.) c. What is the risk-free interest rate for a 4-year maturity? The risk-free rate is 1%. (Round to two decimal places.)
