# If national consumption is $9 trillion when income is$0 and if the marginal propensity to consume is 0.30, what is consumption when disposable income is $20 trillion? To determine To calculate: The national consumption when disposal income is$20 trillion. If national consumption is $9 trillion when disposable income is$0 and marginal propensity to consume is 0.30.

Explanation

Given Information:

The national consumption is $9 trillion when disposable income is$0 and marginal propensity to consume is 0.30.

Formula used:

The integration of function f(x)=xn is given by;

xndx=xn+1n+1+c n1

Here c is any arbitrary constant.

Calculation:

Consider the marginal propensity to consume is 0.30

Since the marginal propensity to consume is 0.30, so;

dCdy=0.30

The equation becomes,

dC=0.30dy

Integrate both sides of the equation,

C=0.30dy=0
