Often, the number of dollars it takes to equal a unit of a particular foreign currency can make the difference between a deal worth doing and a deal that would be a disaster. When the dollar is weak against a foreign currency--meaning it takes more dollars than usual to buy a unit of the foreign currency--it strengthens exporting entrepreneurs. If the entrepreneur keeps prices level, those prices look lower to a buyer dealing in, say, Japanese yen or Mexican pesos.
