(b) Assume that Kmart and Big W are considering whether or not to change their pricing strategies for their department stores. If they both decide to increase prices, Kmart will make a profit of $1 billion dollars and Big W will make a profit of $6 billion. If they both decide to lower prices, Kmart will make a profit of $4 billion dollars and Big W will make a profit of $3 billion. If Kmart lowers prices and Big W increases prices, Kmart will make a profit of $8 billion dollars and Big W will make a profit of $2 billion. If Kmart increases prices and Big W lowers prices, Kmart will make a profit of $10 billion dollars and Big W will make a profit of $6 billion.
