Suppose Megan gets a sales bonus at her place of work that gives her an extra $400 of disposable income. She chooses to spend $300 and save the remaining $100. From this, you can tell that Megan's marginal propensity to consume (MPC) is , and her marginal propensity to save (MPS) is .

0.75, 0.25

Explanation:

With an increase in disposable income marginal propensity to consume increase. Similarly, with an increase in disposable income marginal propensity to save increases. Marginal propensity to save is the amount of money saved or kept after a fraction increase in overall disposable income.

MPC = 300/400=0.75

MPS = 100/400=0.25

Marginal propensity to consume is 0.75

Marginal propensity to save is 0.25

the answer is "b.the increased supply will create a surplus. "

the essential thought behind price controls is straightforward - utilize the power of law to modify the equilibrium of a market. for instance, the legislature may choose that the steel business needs to survive, and in this way pass a law to set a value floor on steel. this implies all steel sold must offer at or over the floor value, which must be set over the equilibrium cost for it to have any impact. the switch could likewise happen - the administration can choose that steel is excessively costly and set a value roof underneath its equilibrium value, with the goal that all steel must be sold at or beneath that ceiling.
