3. C.

Y=C+I+G 1

C = C0 + cYd 2

Yd = Y – T 3




In equation 1, substitute C by equation 2 (C = C0 + cYd)

Y = C0 + cYd + I + G 4

In eqt 4 substitute Yd by equation 3 (Yd = Y- T)

Y = C0 + c(Y – T) + I + G 5

Solve equation 5 to get Y

Y = C0 + cY – cT + I + G

Y – cY = C0 – cT + I + G

Y – 0.5Y = 600 – 0.5*300 + 40 + 280

0.5Y = 770 000

Y = 1 540 000
