Hi. Is what I did correct? If not, can you explain why not and show why

Suppose the current CanadaUK exchange rate is 0.63 pounds (the pound is the UK currency) per dollar, and the aggregate price level is 170 for Canada and 140 for the UK.

• What is the real exchange rate?

What I did: real exchange rate= (0.63 * (140))/170=0.519

• What does this real exchange rate mean in terms of the relative purchasing power of the dollar and the pound?

a. The Canadian dollar buys less "goods" in the UK than it would in the Canada.

b. The Canadian dollar buys the same amount of "goods" in the UK as it would in the Canada.

c. The Canadian dollar buys more "goods" in the UK than it would in the Canada

I said a.
