Final answer:
The marginal propensity to consume is 0.733 and the marginal propensity to save is 0.267. The break-even level of income is $240. The saving situation shown at the $480 level of income is saving.
Step-by-step explanation:
The value of the marginal propensity to consume can be calculated by taking the change in consumption divided by the change in income. In this case, the change in consumption is $240 - $20 = $220, and the change in income is $300 - $0 = $300. Therefore, the marginal propensity to consume is $220/$300 = 0.733.
The value of the marginal propensity to save can be calculated by subtracting the marginal propensity to consume from 1. So, in this case, the marginal propensity to save is 1 - 0.733 = 0.267.
In the table, the break-even level of income is the level of income where consumption equals income. So, in this case, the break-even level of income is $240.
The saving situation shown at the $480 level of income is saving, because saving is positive at that income level.
For each of the following items, the value in the table is constant as income changes: MPS, APC, and APS. The value of MPC is variable as income changes.
