Christa buys a 10-year 1400 par value 5% bond with semi-annual coupons. The price assumes a nominal yield of 5%, compounded semi-annually.

At the end of 10 years, immediately after Christa receives the final coupon payment and the redemption value of the bond, Christa has earned an annual effective yield of 8% on her investment in the bond. Calculate i.

Answer choices: a) 16.9% b) 19.4%
