Four years ago, S$.$ Goodman Corp. issued a bond with a $14\%$ coupon rate, semi$-$annual coupon payments, $$1,000$ face value, and $14-$years until maturity.

a$)$

You bought this bond three years ago $($right after the bond made its coupon payment$)$ when the yield$-$to$-$maturity was $11\%.$ How much did you pay for the bond?

answers: a$)1188\mathrm{.}7,$ b$)1,000,$ c$)1,204\mathrm{.}9,$ d$)726\mathrm{.}8,$ be$)2,161\mathrm{.}3,$ f$)1,227\mathrm{.}8,$ g$)1,211\mathrm{.}8,$ h$)660\mathrm{.}5$

b$)$

Suppose today$$s yield$-$to$-$maturity of the bond is $16\%$ and the next coupon payment is exactly in $6$ months from today. If you sell the bond today, after you have owned it for three years, what would be your capital gain$/$loss yield? Remember, the capital gain$/$loss yield is the return resulting from price changes of your investment.

answers: a$)-2\mathrm{.}1\%,$ b$)0\mathrm{.}0\%,$ c$)-16\mathrm{.}0\%,$ d$)33\mathrm{.}6\%,$ e$)41\mathrm{.}4\%,$ f$)11\mathrm{.}0\%,$ g$)-25\mathrm{.}2\%,$ h$)1\mathrm{.}1\%$

c$)$

Suppose two years from now $($right after the bond made its coupon payment$)$ the bond has a value of $$1,000.$ What would be the yield$-$to$-$maturity of the bond $($APR$,$ semi$-$annually compounded$)?$ Use Excel or a financial calculator to solve this question.

answers: a$)11\mathrm{.}0\%,$ b$)14\%,$ c$)12\mathrm{.}3\%,$ d$)7\mathrm{.}0\%,$ e$)5\mathrm{.}5\%,$ f$)16\mathrm{.}0\%,$ g$)11\mathrm{.}6\%,$ h$)10\mathrm{.}0\%$

I feel pretty confident in my answer for part a$)$ but I keep getting an answer not listed for part b$).$ So I$\text{'}$m attaching my work so far, please try to help me find out where I$\text{'}$m going wrong here
