Consider an economy described by the following: C = $3.3 trillion f = 1 / = $1.3 trillion mpc = 0.75 G = $2.8 trillion d = 0.2 T = $3 trillion x = 0.15 NX = $ -0.5 trillion O B. NX = - 0.75-0.15r. O C. NX = - 1.1-0.75r. D. NX = -0.5-0.15r. An expression for the IS curve is: O'A. Y = 1.4-1.1r. 'B. Y = 17.8-1.4r. O C. Y= 1.4- 17.8r. O D. Y = 17.8-3.3r. If the real interest rate is r=2, equilibrium output Y =$ 15.0 trillion. (Round your response to one decimal place.) If the real interest rate is = 5, equilibrium output Y =$|trillion. (Round your response to one decimal place.)
