Blue Demon Bank expects that the Mexican peso will appreciate against the dollar from its spot rate of $.14 to $.15 in 10 days. The following interbank lending and borrowing rates exist:

      U.S. dollar                     8.0%                       8.3%

      Mexican peso                8.5%                       8.7%

Assume that Blue Demon Bank has a borrowing capacity of either $10 million or 70 million peso in the interbank market, depending on which currency it wants to borrow.
