4. (20) Calculate the requested measures for bond A (assume that bond A pays interest semiannually): Bond: Coupon 7% Yield to Maturity 6% Maturity (years) 7 Par $100

c) Using duration, estimate the price of the bonds for a 100-basis-point increase in interest rates.

d) If convexity is 20, using both duration and convexity to estimate the bond price for a 100- basis-point increase in interest rates.
