Required: What percent of this $53k cost did the company effectively hedge away?

A company wishes to use financial futures to hedge its interest rate exposure. The company will sell 10 Treasury futures contracts at $138k per contract. It is Jul and the contracts must be closed out in Dec of this year. Long-term interest rates are currently 13.56%. If they increase to 14.58%, assume the value of the contracts will go down by 6%. Also if interest rates do increase by 1.45%, assume the firm will have additional interest expense on its business loans and other commitments of $53k. This expense will be separate from the futures contracts. % Do not round intermediate calculations. Input your answer as a percent rounded to 2 decimal places (for example: 28.31%)
