Please help me get the right answers. The Economist publishes a yearly Big Mac Index of currency overvaluation and undervaluation. To illustrate the concept, use the Big Mac Index webpage E. to explore the data for Dec 2014 (note: link will open in a new window). The table below reproduces some of the data from this index. Complete the table with the Implied PPP rate and the valuations. As with most currency rates, carry your results to 4 decimal places (the 'big' and 'small' figures) and always round to two decimal places for percentages. (The Economist rounds differently, so their answers will be slightly different)..
