The tute questions is as follows:

5. (6 points) There are two rms that make the same product. Demand for the product is given by the equation q=402p. The marginal cost of rm 1 is 7, the marginal cost of rm 2 is 3,and neither rm has any xed costs. Suppose that the two rms engage in Bertrand competition in choosing their prices. (a) (2 points) Explain why the prices p1 = 9, p2 = 8 are not a Nash equilibrium for these two rms. (b) (2 points) Explain why p1 = p2 = 3 is not a Nash equilibrium for these two rms. (0) (2 points) Explain why p1 = 192 = 7 is not a Nash equilibrium for these two rms
