The Marginal propensity to consume is 0.4. MPC is the percentage of extra income that an individual consumes.
Therefore,
We are calculating the marginal propensity to consume here (MPC).
Income Change = New Income - Old Income
Income Change = $75,000 - $50,000
Income Change = $25,000
Consumption Change = New Consumption - Old Consumption
Consumption change = $40,000 - $30,000
Consumption change = $10,000 in
Change in Consumption / Change in Income = Marginal Propensity to Consume
Marginal propensity to consume = $10,000 / $25,000
Marginal propensity to consume = 2/5
Marginal propensity to consume = 0.4
Therefore, the Marginal propensity to consume is 0.4.
