If the consumption function is C = 300 +.8(Yd), investment is $200, government spending is $200, t is 0.2, and X = 100 -.04Y then the equilibrium income is: (Hint: Use the equation 1/1-b(1-t) + m a. 6,000 b. 7,500 c. 4,000 d. 2,500 and. 2,000 Consider the previous model, but this time the equation for the investment is 200+ 0.2Y. Then the equilibrium income will be: (hint solve the equation Y = 300+ 0.8((Y - .02Y) +200+ 0.2Y +200 +100 -0.04Y) a. 3,500 b. 2,500 c. 6,500 d. 4,500 and. 4,000
