PLEASE HELP WITH B AND C$.$

A wealthy investor holds $$$$400$ comma $000$ worth of U$.$S$.$ Treasury bonds. These bonds are currently being quoted at $106\%$ of par. The investor is$$ concerned, however, that rates are headed up over the next six$$ months, and he would like to do something to protect this bond portfolio. His broker advises him to set up a hedge using$$ T$-$bond futures contracts. Assume these contracts are now trading at $110-20.$

b$.$It$\text{'}$s now six months$$ later, and rates have indeed gone up$.$ The$$ investor's Treasury bonds are now being quoted at $93\mathrm{.}5\%$ of$$ par, and the$$ T$-$bond futures contracts used in the hedge are now trading at $97-00.$ Show what has happened to the value of the bond portfolio and the profit$($or loss$)$ made on the futures hedge. The profit$($or loss$)$ on the bond portfolio at the expiration date of the futures contracts is $\_\_\_\_\_\_?$

c$.$ Was this a successful$$ hedge? Explain.
