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.

3. A short run cost for a restaurant would paying overtime to waiters who were requested to stay and serve people who came to the restaurant just as it was closing. 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.

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.

7. a) There would be no effect on the marginal cost because the marginal cost is simply the cost to make one more unit of something. In this case that would equal the money to buy gas and the time the driver took to drive someone somewhere and the amount the customer paid. 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.

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.
