Assume that Australia trades mostly with two countries only, the United States and the United Kingdom, and that 65% of the trade is conducted with the United States, 30% with the United Kingdom, and 5% with the rest of the world. The exchange rates of the Australian dollar at two points in time, 0 and 1, are as follows: Exchange Rate Period 0 Period 1 AUD/USD 1.4541 1.7800 AUD/GBP 2.1555 2.5700 i.

Calculate the percentage rates of depreciation or appreciation of the Australian dollar against the two currencies. Comment on your results. [Provide your final answers to 2 decimal points] [15 marks] iii. Calculate the exchange rate relatives, using Period 0 as a base period, and the base value = 100 [Provide your answers to 2 decimal points]. [5 marks] iv.
