The following equations describe an economy. Y = C + I + G. C = 120 + 0.5 (Y – T). I = 100 – 10 r. (M/P)d = Y – 20r. G = 50. T = 40. M = 600. P = 2. From the above list, use the relevant set of equations to derive the LM curve. What are the equilibrium level of income and the equilibrium interest rate? LM: Y = 300 – 20r Y = 300r + 20 Y = 300 + 20r Y = 20r – 300

)murphy was consuming 100 units of x and 50 units of y . the price of x rose from 2 to 3. the price of y remained at 4. (a) how much would murphy’s income have to rise so that he can still exactly afford 100 units of x and 50 units of y ? g
