Today is 1 July, 2019. Hlne has a portfolio which consists of two different types of financial instruments (henceforth referred to as instrument A and instrument B). Hlne purchased all instruments on 1 July 2012 to create this portfolio, which is composed of 21 units of instrument A and 45 units of instrument B. Instrument A is a zero-coupon bond with a face value of $100. This bond matures at par. Its maturity date is 1 January 2029. Instrument B is a Treasury bond with a coupon rate of j2 = 2.02% p.a. and a face value of $100. This bond matures at par. Its maturity date is 1 January 2022. Calculate the current price of instrument B per $100 face value. Round your answer to four decimal places. Assume the yield rate is j = 2.8% p.a. and Hlne has just received her coupon payment. O a. $98.1293 O b. $99.1393 O c. $92.9465 O d. $97.7705
