Assume countries a, b, and c produce goods that are substitutes of each other and that these countries engage in trade with each other. assume that country a's currency floats against country b's currency, and that country c's currency is pegged to b's. if a's currency appreciates against b, then a's exports to c should and a's imports from c should

increase and decrease
