   Assume that last year the Austrian dollar was trading at $.5527, the Mexican peso at $.1102, the United Kingdom (British) pound was worth $1.4233. By this year the U.S. dollar value of an Australian dollar was $.7056, the Mexican peso was $.0867, and the British pound was $1.8203. Calculate the percentage appreciation or deprecation of each three currencies between last year and this year. Please show how you came up with the answer!! Thanks
