Answer:

The economy's MPC is 0.8

Explanation:

Marginal propensity to consume [tex]MPC = \frac{mC}{mY}[/tex]

Where:

  • mC is marginal consumption, ie. the additional consumption spending as a result of additional disposable income
  • mY is marginal income, ie. the additional disposable income

Marginal consumption is $32 billion, marginal income is $40 billion, so MPC = 32/40 = 0.8
