Answer:
The euro appreciated against the dollar, or increased its relative price against the dollar.
The pound depreciated against the dollar, or decreased its relative price against the dollar.
Step-by-step explanation:
let's assume that both the euro and the pound trade at 1 per $1.50, and the Spanish buyer owes €100 to Angela, while Angela owes £100 to a British vendor.
Since the euro appreciated, it gained value, it now trades at $1.60 for €1, so Angela will receive $160 from the Spanish buyer instead of $150.
Since the pound depreciated, it lost value, it now trades at $1.40 for £1, so Angela will pay $140 to the British vendor instead of $150.
