Planning a Trip to Japan

Passport and YenYou and your family had a foreign exchange student from Japan live with you during your freshman year in high school. You are planning to visit her over an extended spring break. You emailed her and asked her about your estimated expenses for your trip. She has just emailed you back. The only problem is that she answered all of your questions in yen, not in U.S. Dollars. You grab the business section of the newspaper to check the foreign exchange rate for the Japanese Yen. Listed below are the anticipated expenses for your trip. How many U.S. Dollars will you need to exchange for the Japanese Yen? You may plan to use a credit card or an ATM machine in Japan, but you will still need to know the estimated cost of your trip.

Your airline ticket costs $1000 round trip. You will be staying for two weeks. One week you will stay at your friend's parents' home. You will travel for one week. You will be staying in hotels and sightseeing. You will also be eating out. You will need to bring some gifts back for your family.

Here is the information from the email message.
