You are considering buying a bond with a $15-$year maturity that has a face value of $$1000$ and a coupon rate of $8\%$

$($semi$-$annual payments$).$ What cash flows would you pay and receive from your investment if the yield to maturity

on the bond is $6\%$ now and $7\%$ when you sell it $2$ years from today $($just after a coupon is paid$)?$
