If an exchange rate is £1= 2.03 american dollars £1= 2.15 canadian dollars how many more canadian dollars than american dollars do you get for £250

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.

Ibelieve that c. recording would work best.
