If you can do it fast will be really nice, Thanks in advance

1.(20%)Calculate the requested measures in parts (a) through (b) for bonds A and B (assume that each bond pays interest semiannually): Bond A Coupon 6% Yield to maturity 8% Maturity (years) 2 Par $100,00 Price $80.00 (a) Compute the approximate duration for bonds A using the shortcut formula by changing yields by 18 basis points (b) Compute the approximate convexity measure for bonds A using the shortcut formula by changing yields by 18 basis points
