Please help with the last question: If government purchases increase to $4.2 trillion and the real interest rate r=3, equilibrium output Ye = $____trillion.

= F = 0.5 mpc = 0.7 = = $3.3 trillion 1 = $1.2 trillion G = $3.5 trillion = $3 trillion NX = $ -0.5 trillion d = 0.3 = x = 0.15 The simplified expression for the consumption function is: A. C=3.3+0.7Y. B. C= 1.2 +0.7Y. C. C= 3.3+ (1 -0.7)Y. D. C= 1.2 + (1 -0.7)Y. The simplified expression for the investment function is: O A. 1 = 1.05 -0.7r. OB. 1 = 3.3-0.3r. O C. 1 = 3.3 -0.7r. l = D. J = 1.05 -0.3r. The simplified expression for the net export function is: O A. NX = - 1.05-0.7r. B. NX = -0.7 -0.15r. C. NX = -0.5-0.15r. OD. NX = -0.15 -0.5r. An expression for the IS curve is: A. Y = 17.5 - 1.5r. B. Y = 17.5 - 3.3r. C. Y = 1.5 - 17.5r. D. Y = 17.5 1.05r. If the real interest rate is r= 3, equilibrium output ve = $ 13 trillion. (Round your response to one decimal place.) If the real interest rate is r=6, equilibrium output ve = $ 8.5 trillion. (Round your response to one decimal place.) = If government purchases increase to $4.2 trillion and the real interest rate r= 3, equilibrium output Ye = $ = trillion. (Round your response to one decimal place.)
