| | 1. Fixed cost can be easily identified by seeing what the total cost are when the ouput is zero. An example of variable cost in a restaurant would be the cost of food, additional employees, and energy that increase as the business grows. | | 1.

| | + | :Excellent. (Spelling: "output", not "ouput"; grammar: "total cost IS", not "are") |

| | 2. The plan would fail because there is a decreasing returns of scale in the restaurant, because more waitresses would result in more wasted time talking to each other and waitresses getting in the way of each other. | | 2.

| | 3. An example of a short run cost in a home school would be the cost of purchasing books, learning aids, etc. for a preschool child to help teach them the basics. A long run cost with a home school is continuing to purchase what is needed to properly teach the child through the years so they are equipped and prepared to go out into the world, get a job, and be a productive member of society. | | 3.

| | + | :Not quite. You understand the differences in time between the two, but there is also a difference in the type of goods purchased. See model answer when available. (Minus 1). |

| | 5. In the short run, it may cost quite a bit of money to get a degree from college, but in the long run, the money, time, and effort pays off with more marketable skills and ultimately a better job and quality of life. | | 5.

| | 6. Your fixed cost would be $1,000,000 for the factory. Your average variable cost would be $20,000 (1,000,000/50) Your average total cost would be $40,000 ($1,000,000 fixed + $1,000,000 variable/50 cars) Your Marginal cost would be $19961 ($1,000,000 + $18000/51) | | 6.

| | + | |
| | + | :All correct until the marginal cost. It is simply the $18,000 paid to make the 51st car. (Minus 1). |

| | 7. When the fee is raised to $1200 marginal cost, average variable cost, and average total cost would all increase. | | 7. When the fee is raised to $1200 marginal cost, average variable cost, and average total cost would all increase. |
| | + | |
| | + | :Nope on two out of three. Only the average total cost increases, because the license is a fixed cost independent of output (number of car riders). When output is 0, the license cost is still the same. (Minus 2). |

| | 8. By watching TV for an hour instead of working and earning $8/hour, your accounting loss would by $8 plus an unknown amount of explicit cost for things such as electricty to run the TV. The economic loss would not be possible to figure out without additional information. | | 8.

| | + | |
| | + | :Nope, accounting loss is $0 and the economic loss is $8, because economic loss factors in the opportunity cost. (Minus 2) |

| | + | :64/70, with some good answers. Please be sure to review the model answers when available after Sunday. Our midterm exam will be a week from this Thursday. Thanks.--[[User:Aschlafly|Andy Schlafly]] 19:54, 24 October 2009 (EDT) |
