#7

ExplanationFocuses on effects of small changes.
#16
What does the law of diminishing marginal utility suggest?
The more units of a good consumed, the smaller the additional satisfaction gained from each additional unit.
ExplanationDecreasing additional satisfaction with more consumption.
#17
Which of the following scenarios best illustrates the application of marginal analysis?
