Question 6

2.71 / 2.71 pts
I had a full time job this summer where I earned $10 per hour. It costs me about $4 in gas money for every round trip to and from campus, which lasts for one hour. My class meets once a week and lasts 3 hours. My opportunity cost (including both direct and indirect costs) of attending class in any given week is:






Direct costs would be costs that require an outlay of money, such as gas costs = $4 per trip/week.

Indirect costs are “hidden” costs, which represent an opportunity someone gives up to obtain something else (known as “opportunity cost” by economists). In this case by attending the class for 3 hours and driving to and from campus for one hour, one gives up 4 hrs, which he/she could have worked and earned $10 per hour, thus a total of $40.

The sum of the two costs above would yield what you are asked to find for this question.

The table below gives information about the relationship between two variables x and y. The the slope of the relationshipequals ______.

X         Y

2          180

4          184

6          188

10        196


Slope = (Change in Y) / (Change in X) = (184-180) / (4-2) = 4/2 = 2. You could have used any two other X points and their corresponding Y points to find that the ratio is the same (= 2).
