From the following data about an economy, calculate (a) equilibrium level of national income and (b) total consumption expenditure at equilibrium level of national income.

Given, consumptin function, C= 200 + 0.5Y. Investment, I = 1,500
We know that, `Y = C + I`
`Y = 200 + 0.5 Y + 1,500 or Y = 1,700 + 0.5Y`
or `0.5Y = 1,700 " " or Y = 1,700 xx (10)/(5) = 3,400`
(a) Equilibrium level of National Income, `Y = 3,400`
(b) Total Consumption Expenditure, `C = 200 + 0.5Y`
`= 200 + 0.5 (3,400)`
`= 200 + 1,700 = 1,900`
