Suppose that you can purchase satellite TV service for a fixed monthly fee of $79, no matter how many hours of TV you watch. Assuming that the principle of diminishing marginal benefit applies to watching TV, the optimal (efficient) number of hours of TV to watch per month is:
Group of answer choices
Zero
The number of hours where marginal benefits are zero.
The number of hours where marginal cost is lowest.
The number of hours where marginal benefits are maximized.
You are the manager of a firm that specializes in small single-board widgets.Your goal is to determine the number of units (Z) that must be produced and sold by your firm each month in order to maximize profits. The total benefits (revenues) and costs to your firm of producing various quantities are given in the first three columns of the following table. Based on this scenario, complete the table and answer the accompanying questions:

- Your business produces two products: graphics and writing assessments. However, time is finite and your business must allocate its time between the two products. If your business is producing one service, it cannot produce the other service at the same time. Based on previous experience, you know that your firm can produce 11 graphics and 20 assessments per day. Your firm could also produce 7 graphics and 40 assessments per day. Given these production possibilities, what is the tradeoff between your two services? Make sure you estimate your tradeoff (opportunity cost) in terms of how much you receive for each unit of graphics services that you give up, that is, for 1 unit of graphics given up, how many units of assessments do you gain? Make sure to express your answer to the first decimal point.arrow_forwardWhen marginal cost is greater than marginal benefit at the current activity level, the decision maker can increase net benefit by decreasing the activity because total cost will fall by more than total benefit will fall. net benefit is upward sloping at this point. marginal cost is rising faster than marginal benefit is falling. total benefit will rise by more than total cost will rise.arrow_forwardMaria can purchase shirts for $22.00 each. She considers the benefit of one shirt to be $40.00, but with each additional shirt she purchases the benefit decreases by $5. According to the Principle of Optimization at the Margin, Maria will purchase... shirts. (Enter your response as a whole number.)arrow_forward

Their room can easily get messy, and their parents are always telling them to tidy it. Here are the costs and benefits to both Becky and Sarah of taking the time to clean their room: If both Becky and Sarah clean, they each spend two hours and get a clean room. If Becky decides not to clean and Sarah does all the cleaning, then Sarah spends 10 hours cleaning (Becky spends 0) but Sarah is exhausted. The same would occur for Becky if Sarah decided not to clean—Becky spends 10 hours and becomes exhausted. If both girls decide not to clean, they both have a dirty room. What is the best outcome for Becky and Sarah? What is the worst outcome? (It would help you to construct a prisoner’s dilemma table.)arrow_forwardBecky and Sarah are sisters who share a room.

- Is this example also an example of economically rational decision making? “In 2019, I started my small business by selling prints of my photographs. Now it’s temporarily closed. During this time I had the option of shipping my prints through USPS or UPS. I decided to ship my prints through USPS instead of UPS since it was a bit expensive at the time. My prints that were shipped out from USPS arrived in time and came in good condition. The opportunity cost is the cost of UPS shipping.”arrow_forwardYou are the manager of a firm that specializes in small single-board widgets.
