since 1 us dollar is=1.32 Canada dollars .
100 us dollars needs to be converted to the Canadian dollars which is 132 canadian dollars, and the total expenses subtracted ( 50 + 10=60 )from it, then it is subtracted from 132 and the remainder is 72 . We will have 72 converted back to us dollars ( divided by 1.32) the final answer gives 54.54 us dollars.
