Using data from The Economist's Big Mac Index for 2019, the following table shows the local currency price of a Big Mac in several countries as well as the actual exchange rate between each country and the United States. At the time of the data collection, a Big Mac would have cost you $5.74 in the United States and GBP 3.29 in the United Kingdom. The actual exchange rate between the British pound and the U.S. dollar was $1.25 per pound. The dollar price of a Big Mac purchased in the United Kingdom was, therefore, computed as follows:
Dollar price of a Big Mac in the United KingdomDollar price of a Big Mac in the United Kingdom

For the price you paid for a Big Mac in the United States, you could have purchased a Big Mac in the United Kingdom and had some change left over for fries!
Complete the final column of the table by computing the dollar price of a Big Mac for the countries where this amount is not given.

Purchasing-power parity (PPP) theory states that exchange rates would need to equalize the prices of goods in any two countries. For the dollar price of a Big Mac to be the same in both countries, a U.S. citizen would need to be able to convert $5.74 into exactly GBP 3.29. To find the exchange rate at which hamburger purchasing power is the same in both countries, divide the price in the United States by the price in the United Kingdom:
PPP Exchange Rate (U.S. Dollars per British pound)PPP Exchange Rate (U.S. Dollars per British pound)

The exchange rate that would have equalized the dollar price of a Big Mac in the United States and the Euro area (that is, the PPP exchange rate for Big Macs) is . This change would mean that the euro had against the dollar.
