The consumption function of an economy is as follows, where C(x) is the personal consumption expenditure and x is the personal income, both measured in billions of dollars.
C(x) = 0.644x + 83.61
Find the rate of change of consumption with respect to income, dC/dx. This quantity is called the marginal propensity to consume.
