Two ice cream firms

Question 6 [6 points] There are two ice cream firms in a townI Ben and Jerry, and the demand for ice cream is p = 30 - 0:10, where Q is the total amount of ice cream produced by both firms. The marginal cost of production is constant at $4 per unit of ice cream for both firms. Each firm has three strategies of production: low output {20 units], medium output [30 units) and high output [40 units]. Based on the demand function and marginal cost, write down the Hanna;f form payoff matrix of this two-firm, th ree- strategy game. What is the Nash equilibrium of this game? Is this game considered a prisoner's dilemma game
