In an ongoing price war between burger haven (locally owned) and macarches (a chain), both restaurant managers plan to change the price of a hamburger by 10¢. if they both raise their prices, there will be no change in their market shares, but if they both lower their prices, the chain's national advertising will ensure that macarches gains 4% of the market. again because of advertising, if burger haven lowers their price and macarches raises their price, burger haven will gain only 2% of the market, but if burger haven raises their price and macarches lowers their price, macarches will gain 10% of the market. use this information to decide what the managers should do. macarches l r burger haven l r % % % %
