in the terms of the original question.
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 7% of the market. Again because of advertising,
if Burger Haven lowers their price and MacArches raises their price, Burger Haven will gain only 5% of the market, but if Burger
Haven raises their price and MacArches lowers their price, MacArches will gain 8% of the market. Use this information to decide
what the managers should do.
What does L represent?
L represents lowering the price by 10¢.
L represents raising the price by 10¢.
What does R represent?
