Consider the following short-run IS-LM model with income taxation. The economy is described by equations (1) through (6). (Note that there are 25% income taxes in this model).: (1) C = 300 + 0.8(Y - T); (2) T = 100+0.25Y; (3) G = 1400; (4) I = 1000 - 40 r ; (5) Y = C + I + G ; (6) M/P = 0.5Y - 50r where the nominal money supply M=2000 and the price level is P = 1. 12. In the short run, the equilibrium output for this economy is given by (approximately): A) Y* = 3975.85 B) Y* = 2524.00 C) Y* = 5275.00 D) Y* = 8550.00
