PLEASE MAKE SURE TO EXPLAIN THE process of a money market hedge. Ive already posted this and the other person did not fully answer.

IBM purchased computer chips from NEC, a Japanese electronics concern, and was billed 250 million payable in three months. Currently, the spot exchange rate is 105/$ and the three-month forward rate is 100/$. The three-month money market interest rate is 8 percent per annum (2% for three-months) in the U.S. and 7 percent per annum (7%/4 for three months) in Japan. The management of IBM decided to use the money market hedge to deal with this yen account payable. Explain the process of a money market hedge and compute the future dollar cost of meeting the yen obligation. Thanks! I will unvote von
