remaining $140.
From this, you can tell that Cho's marginal propensity to consume (MPC) is
and her marginal propensity to save (MPS) is
0.80,
0.80,
Mathematically, it must always be true that:
0.56,
0.56,
0.20
Consumption
=
Disposable income-Saving,
Saving-Disposable income,
Disposable income+Saving
0.20
Or 0.14
Or 0.14
Therefore, it must also be true that:
MPC
1-MPS,
1+MPS,
OR
