Consider an economy described by the following: C = $3.25 trillion moc = 0.8 / = $1.3 trillion = 0.3 G = $3.5 trillion X = 0.2 T = $3 trillion 2 = 1 NX = $ -1 trillion T = 1 f = 1 The expression for the MP curve is: O A. (=3 + 1x. O B. (= 3 + 0.8x. O C. (= 1 + 0.8x. D. F=1 + 17. The expression for the AD curve is: O A Y= 15-1.3. OB. Y= 19.25 - 1.3x. C. Y= 19.25- 2.5x. OD. Y= 15 -2.5x. Assume that * = 1. The real interest rate is |%. (Round your response to two decimal places.)
