You have the option to play tennis or a round of golf (but not both). The tennis match requires you to take 2 hours off from work and the round of golf requires you to take 4 hours off from work. Playing tennis has value to you equal to $40, while golf has value to you equal to $115. Tennis courts are publicly available at no cost, but golf costs $40 per round. Suppose your wage from working is $88 per hour. The net benefit from playing tennis is $___________ and the net benefit from playing golf is $___________. Therefore, you should play ________ (tennis, golf)
24, 43, golf
You are a professor of economics at a university. You've been offered the position of serving as department head, which comes with an annual salary that is $9,500 higher than your current salary. However, the position will require you to work 200 additional hours per year. Suppose the next best use of your time is spending it with your family, which has value of $20 per hour. What is the difference in the net benefit from becoming the department head? The change in net benefit is $____________. (just number) To optimize, you ___________ (should/shouldn't) become a department head.

You are hired as a consultant for a local restaurant. It is considering whether to close at 9:00 p.m., stay open an extra hour (10:00 p.m.), or close earlier (8:00 p.m.). Based on wages and utility bills, the added cost (the marginal cost) of staying open for each additional hour is $482. If the additional revenue (the marginal revenue) during the last hour is $542, the profit earned during the last hour of operation will be $ _____. If the additional revenue during the last hour is $382, the profit earned during the last hour of operation will be $______. If the additional revenue (the marginal revenue) from staying open until 10.00 p.m. is $482 the profit earned during the last hour of operation will be $________

increase and net benefit would decrease
When optimizing for total value, opportunity cost must be ___________ ________ (added to, subtracted from) total cost. Assuming __________ (varying, equal) benefits, the lowest cost option is the optimal choice.
added to, equal
Suppose you have just landed a job near the center of a city and you now need to decide where to live. If you live close to the city center, your round-trip commute will be 15 minutes. If you live in the distant suburbs, your round-trip commute will be 60 minutes. There are lots of workers like you who work downtown. Since there are only a limited number of apartments near the city center, these apartments will be allocated based on ________ (only the costs, only the benefits, both the costs and benefits) that you face. This process is known as ____________________ ("more bang for your buck, "optimization, differentiation.)
both the costs and benefits, optimization
Determine if the following statements better describe optimization in levels or optimization in differences. John is attempting to decide on a movie.

You and your friend, Jim, have just moved out of your dorm and into a new apartment. Both of you decide that you need to get a couch. Jim thinks you should get a new one from a furniture store nearby. You feel that, given your budget, it is best to buy a used one. Your other options are to buy one online or get a couch custom-made at the same furniture store. How would you arrive at an optimal solution here? Assume that your opportunity cost of time is $5 per hour. You and Jim would need to consider ___________. A. only the price of each couch. B. only the marginal benefit of each couch. C. the indirect costs of traveling to the furniture store and the opportunity cost of your time required to shop. D. the direct costs of the price of each couch and the cost of having each couch moved to your apartment. E. the direct costs and the indirect opportunity cost of your time required to shop Now suppose that you have a summer job that pays you $15 per hour. How would your analysis change? With a $15-per-hour summer job, ___________ would increase. a. the price of the couch b. the fuel cost of traveling c. the opportunity cost of your time d. the cost of having the couch moved
the direct costs and the indirect opportunity cost of your time required to shop, the opportunity cost of your time
Advances in wireless communication technology reduce the non-financial costs of long commutes: People who ride trains can get work done, and people who drive cars have more entertainment options. Given this information, which of the following will be an effect on the geographic area of cities? A. The total cost of commuting from any given distance to work will increase because the indirect cost of the commute will rise. B. The total cost of commuting from any given distance to work will reduce because the direct cost of the train ticket will fall. C. The total cost of commuting from any given distance to work will reduce because the indirect cost of the commute will fall. D. The total cost of commuting from any given distance to work will increase because the direct cost of the train ticket will rise. How will this result impact people as they decide how close to live to the city where they work? They will be: a. more willing to locate farther from the city b. more likely to locate closer to the city c. unaffected by this when making location decisions
the total cost of commuting from any given distance to work will reduce because the indirect cost of the commute will fall, more willing to locate farther from the city
