The head of your department is a prominent researcher. A health research foundation has asked him travel to London to give an important speech at a conference. He will then travel to Paris to tour a research facility before returning home. Although his travel expenses are being funded by the foundation, he will still need to take along some personal money. Consequently, he asks you to figure the exchange rates for $500 and for $1,000 in both pounds and euros. He explains that he is trying to judge the spending power of U.S. dollars when converted to the other currencies so he can decide how much personal money to take on the trip.
