Final answer:
The British Pound was weaker against the U.S. dollar in 2017 than in 2008, as its value decreased from $2.00 to $1.27. This indicates that the dollar appreciated against the pound.
Step-by-step explanation:
Based on the currency conversion table provided, the equivalent amount in dollars for 1 British Pound varies depending on the time frame:
In 2008, 1 British Pound was equivalent to $2.00 in U.S. dollars.
In 2017, this amount had changed to $1.27 in U.S. dollars.
Now, if we consider these values, the British Pound was weaker against the dollar in 2017 compared with 2008. Consequently, this means that the dollar had appreciated versus the pound because you would need fewer dollars to buy the same amount of British Pounds in 2017 than you did in 2008.
