Boeing Corporation has just issued a callable $($at par$)$ three$-$year, $5\%$ coupon bond with semiannual coupon payments. The bond can be called at par in two years or anytime thereafter on a coupon payment date. It has a price of $$99.$ What is the bond's yield to maturity and yield to call?

$[$IN EXCEL: please show all work and formulas It also needs to be able to work if values change $(\%$coupon, semi$/$annual$/$monthly payments, price, etc...$)$

Thank you!
