Before boarding his flight to Zurich, Switzerland, Juan purchased CHF800 from his bank when the exchange rate was C$1 = CHF0.9712. However, Juan had to cancel the trip. Juan returned to the bank to convert the Swiss currency back into Canadian dollars. If the exchange rate changed to C$1 = CHF0.9952, how many Canadian dollars would Juan have lost in these transactions? Assume the bank has a 1.90% commission on both the sale and the purchase of the funds
