Bill and alma are shopping for their first home. they have found two houses that are nearly identical except for their locations. one house costs $250,000 and is 15 miles from their places of employment. the second house costs $275,000, but it is within 5 miles of where they both work. now bill and alma are trying to decide if living 10 miles closer to their workplaces is worth the extra $25,000 in the cost of the house. which decision-making concept are they using?
a. total utility
b. opportunity cost
c. marginal analysis
d. time value of money

The correct answer is c. Marginal analysis

Explanation:

Marginal analysis is a technique you can apply when you are comparing some options.  We can say this analysis is an examination of the additional benefits of an activity compared to the additional costs incurred by that same activity. Using this technique you can maximize the potential profits.

The additional cost versus the additional benefit of a decision. In this case,  Bill and Alma are analyzing if  living 10 miles closer to their workplaces ( benefit) is worth the extra $25,000 in the cost of the house(cost). This is marginal analysis.
