The macroeconomy of a country is shown as follows C = 300 + 0.75 (Y - T) I = 100 G = 200 NX =75 T = 100 (T applies to taxes; NX is net exports.) The equilibrium national income Y for this economy is (i). Since the government expenditure multiplier is (ii), the equilibrium national income is (iii) when government expenditure G is 225.

(i)A. 2100 B. 2200 C. 2400 D. 2500

(ii)A. 3 B. 4 C. 5 D. 6
