| | 1. Fixed costs can be easily identified by seeing what the total costs are when the output is '''zero'''. An example of a variable cost would be the amount of money needed to pay employees their wages. This amount can vary as the employees quit their job, are hired or given raises. | | 1.

| | + | :Good, but your explanation of "variable cost" is slightly off. It's called "variable" because it varies with a change in OUTPUT, not something else. (Minus 1). |

A long run cost for this restaurant would be to hire and train new waiters who would take a later shift to keep the restaurant open later every night. | | 3.

Obtaining a college degree would be expensive and time-consuming in the short run, however in the long run it would pay off since you would be more likely to get a better job and make more money than someone who does not have a degree. | | 5.

| | 6. The fixed cost would = $1,000,000 for the building; The average variable cost would also be $1,000,000 for the materials, labor, and electricity; The average total cost would be $2,000,000 with the cost of the building plus the materials, labor, and electricity added together. The marginal cost to make the 51st car would be $18,000 since that is how much it costs to make the 51st car. | | 6.

| | + | :Your variable and total costs are not properly ''averaged'' over the output. Average variable cost is Total variable cost divided by the number of units: 1,000,000 divided by 50 units = $20,000 per unit. Average total cost is Total cost divided by the number of units: $2,000,000 divided by 50 units = $40,000 per unit. Your MC is correct. (Minus 2). |

| | 7. a) There would be no effect on the marginal cost. b) there would be an increase in the average variable cost because the license fee is not a fixed cost and its price rose. c) the average total cost would increase since there is an increase in the average variable cost which includes the license fee. | | 7. a) There would be no effect on the marginal cost. b) there would be an increase in the average variable cost because the license fee is not a fixed cost and its price rose. c) the average total cost would increase since there is an increase in the average variable cost which includes the license fee. |
| | + | |
| | + | :(A) is correct. (B) is not correct because license fees are not variable costs dependent on output. There is no effect on variable cost here. (C) is correct. (Minus 1). |

| | 8. My accounting profit or loss for that hour of watching television is equal to the total revenue minus explicit costs. The total revenue = $0; The explicit costs (since we're not talking about opportunity costs) would also be $0. Thus, the accounting profit or loss is nothing since 0 minus 0 = 0. My economic profit or loss is equal to the time I spent and the opportunity cost. So, in this case that would equal 1 hour - $8. So, I lost an hour of my time and $8. | | 8.
