Before boarding her flight to Zurich, Switzerland, Katherine purchased CHF800 from her bank when the exchange rate was C$1 = CHF0.9642. However, Katherine had to cancel the trip. Katherine returned to the bank to convert the Swiss currency back into Canadian dollars. If the exchange rate changed to C$1 = CHF0.9918, how many Canadian dollars would Katherine have lost in these transactions? Assume the bank has a 1.50% commission on both the sale and the purchase of the funds
