A British sweater costs 75 pounds in London. An American jean costs $80 in Los Angeles. At an exchange rate of 0.76/$, what is the price of a sweater in terms of a jean? All else equal, how does this relative price change if the dollar depreciates to 0.50/$? Compared with the initial situation, has a jean become more or less expensive relative to a sweater? If consumers in the U.S. and the UK view a sweater and a jean as perfect substitutes, what would happen to the demand for the jean after this relative price change? (Whenever necessary, round your numbers to two decimal places.)
