#### Solution

C = 40 + 0.8 YD

T = 50

I = 60

G = 40

X = 100

M = 50 + 0.05Y

"Equilibrium income"(Y) = A/(1 - c + m)

= (C - cT + I + G + X - M)/(1-c+m)

= (40-0.8xx50+40+60+100-50)/(1-0.8+0.05)

= (40-40+40+60+100-50)/0.25

=150/0.25 = (150xx100)/25 = 600

Net export balance NX = X − M − 0.05Y

= 100 − 50 − 0.05 × 600

= 50 − 0.05 × 60

= 50 − 30 = 20
