Perekonomian 3 sektor (Pajak proposional) Diketahui C = 225 + 0,35Yd I = 120 G = 95 Tx = 12 + 0,2y Tr = 15 Hitung a. pendapatan nasional keseimbangan b. konsums

C = 225 + 0,35(Y-12-0,2Y+15)
C = 225 + 0,35(0,8Y+3)
C = 225 + 0,28Y + 1,05
C = 226,05 + 0,28Y
a) Y = C + I + G
Y = 226,05 + 0,28Y + 120 + 95
Y - 0,28Y = 441,05
0,72Y = 441,05
Y = 441,05 / 0,72
Y = 612,569
b) C = 226,05 + 0,28(612,569)
= 226,05 + 171,519
= 397,569
c) S = -225 + 0,65(0,8Y+3)
= -225 + 0,52Y + 1,95
= -223,05 + 0,52(612,569)
= -223,05 + 318,536
= 95,486
