The following equations describes an economy:

Y = C + I + G + X - M [where X=exports, M=imports]

C = 250 + 0.7*(Y - T)

T = 30

I = 300

G = 60

X = 40

M = 100 + 0.2*(Y - T)

Which of the following statement is true?

Group of answer choices

Without any changes, the equilibrium level of Y is 2167.

If exports increase by 10, equilibrium Y will increase by 20.

The value of the government spending multiplier is 3.33.

If government spending increases by 40, equilibrium Y will increase by 333.
