Comparison of prices or costs across different country and currency environments requires the translation of the local currency into a single common currency. This is most meaningful when the comparison is for the identical or near-identical product or service across countries. Deutsche Bank has recently started publishing a comparison of cheap dates -- and evening on the town for two to eat at McDonald's, see a movie, and drink a beer. Once all costs are converted to a common currency, the U.S. dollar in this case, the cost of the date can be compared across cities relative to the base case of a cheap date in USD in New York City.

After completing the table below, answer the following questions.

a. Which city in the table is truly the cheapest date?

b. Which city in the table is the most expensive-cheap date?

c. If the exchange rate in Moscow on the Russian ruble (RUB) was 0.04200, instead of 0.0283, what would be the USD price?

d. If the exchange rate in Shangahi was CNY 6.66 = 1 USD, what would be its cost in USD and relative to a cheap date in New York City?
