Disposable Income Consumption $10,000 $12,000 18,000 18,000 26,000 24,000 34,000 30,000 42,000 36,000 50,000 42,000

Explanation / Answer

1. Option 3. 0.75

Explanation: Marginal propensity to consume = change in consumption/change in income.

From the table, we can see that for every $8,000 increase in disposable income, consumption increases by $6,000.

So, the marginal propensity to consume = change in consumption/change in income = $6,000/$8,000 = 0.75.
