How do I solve? Investment = 100, government expenditure = 75, net taxes fixed at 100, and consumption (C) is the function C = 25 + 0.8Yd where Yd is disposable income and Y is GDP.
Y = C + I + G
C = 25 + 0.8*Yd
Yd = Y  100
Y = 25 + 0.8 * (Y  100) + 100 + 75
Solve(Y )
government expenditure multiplie by different equation Y = C + I + G. dY/dG = 1 / (1  c) where c is the marginal propensity.to consumr
c=0.8........ ans
thanks but not really ok with it...this is the real question...
suppose that for a particular economy ,investment expenditure i=100,government expenditure G=75, and tax T=100 in adition personal consumption expenditure is C is given in a function below
c=25+0.8yd
a..what is the level of equilibrium
b.what is the value of expenditure multiplier
c.what is the value of tax multiplier

ok i help u .................. wait
im still waiting
Level of eqlibrim;
A" consumar who is having a fixed incom and the price of the good are also fixed will attain equilbrium when the spends his money incom on different goods in sch a way that the rations of MU of the last units of the goods purchasased and their prices are equl".
Expenditurre multiplier;
Expenditure multiplier, measur the change in aggregate demand and expenditur.
simple expenditure include is the ratio change in aggregate demand.
Value of tex multiplier;
information to clculate the multiply expentidure is 1/mpc=175=25
solution
G(goverment)=75
I(Investment)=100
T(tax)=100
YD is disposbl incom GDP. wear (GDP) gross domastic production.
solution;
Y = C + I + G
C = 25 + 0.8*Yd
yd=y1000
Y = 25 + 0.8 * (Y  100) + 100 + 75
Solve
equation Y = C + I + G. You get dY/dG = 1 / (1  c) where c is the marginal propensity to consume., c = 0.8.
best my work i explain full work............. no issu thanks
