Correct option is D.

$1440

Explanation:

Equilibrium output in this economy equals

Y=C+I+G+NX

C=a+b (Y-T)

a=autonomous consumption=100

b=marginal propensity to consume = 0.75

Y=equilibrium GDP

T=taxes=40

I=investment = 50

G=government spending = 150

NX=net export = 20

Y=100+0.75 * (Y-40) + 50+150+20

Y=320+0.75Y-30

0.25Y=290

Y=290/0.25

Y=1160

the equilibrium GDP is $1160
