If the exchange rate changed to C$1 = A$1.0426, what was the change in value of the computer in Australian dollars?

A U.S. firm, sells merchandise today to a British company for £100,000. The current exchange rate is $1.38/£, the account is payable in three months, and the firm chooses to hedge by borrowing £98,765.43 today and exchanging the proceeds today for dollars; the loan will be paid back with the £100,000 accounts receivable (money market hedge). If Husky converted the borrowed pounds into dollars today and invested that amount at its WACC of 6% (1.5% for 90 days), how much much money in U.S. dollars will Husky Sporting Goods Company have in 90 days?
