Provide step by step explanations to the following questions.

1. Given the following simultaneous game. fore for the Nash equilibrium . Be sure to use the probabilities assigned L / y R / 1 - y T / x 101 5 2 1 10 B / 1-X 8 1 4 41 2 2 Two duopoly firms face. market demand of y= 25 - 1/2 P. Given that the firms face a marginal cost of us dollar to per output. Find 4, and iGiven the following equations from a certain economy: C = 100 + 0.8Y (Consumption function) | = 10-10r (Investment function) L = Y-100r (Real money demand) G = 10 (Government purchases) T = 0.25 (Tax rate) M = 295 (Real money supply) Required i.) Calculate the monetary multiplier policy and interprate it. ii.) Suppose equilibrium income increases by 40, by how much must real money stock increases for the new level of income to be in equilibrium
