Answer 1

the easy way.
2.03×250=507.5
2.15×250=537.5
537.5-507.5=37
you get 37 more Canadian Dollars than American Dollars

Answer 2

Here is the easy way to answer this:

For each single £, you get (2.15 - 2.03) = 0.12 Canadian dollar more.

250 of those add up to (250 x 0.12) = 30 Canadian dollars more.
