A weapons producer sells guns to two countries that are at war with each other. The guns can be produced at a constant marginal cost of $10. The demand for guns from the two countries can be represented as: QA = 100 - 2p QB = 80 - 4p A. Why is the weapons producer able to price discriminate? B. What price will it charge to each country? C. Assume the fixed cost is zero so the total cost is TC(Q)=10Q. What is the joint profit of the weapon producer
