Economics Concept Introduction
Complement goods: Complementary goods are those goods that are demanded together.
(b)
To determine
Relationship between price of winter coats and sale of winter coats.
(b)
Expert Solution
Explanation of Solution
There is a negative relationship between price of winter coats and sale of winter coats because when the price of coat increases, people would demand less quantity. Thus, increase in price reduces the quantity of coat sale and vice versa.
Economics Concept Introduction
Negative relationship: A negative relationship refers to the situation where two variables move in the opposite directions.
(c)
To determine
Relationship between price of personal computer and production of personal computer.
(c)
Expert Solution
Explanation of Solution
Quantity of production depends upon the price of that good. Thus, there is appositive relationship between price of computer and quantity of computer produced. Increase in price of computer leads to increase in the production of computer or quantity supply of computer in the market.
Economics Concept Introduction
Positive relationship: A positive relationship refers to the situation where two variables move in the same direction.
(d)

- Wolfgang is a typical producer in a perfectly competitive piano industry (i.e., all other producers of pianos face the same costs as Wolfgang). The following production and cost data apply to the long run as well as the short run. Fixed costs (rent) are unrecoverable in the short run and are equal to $2400 per month. Variable costs consist of raw materials (wire, wood, plastic), which cost $1000 per piano, and the $40 per hour opportunity cost of Wolfgang's time. Wolfgang's production function is given in the table at right. Wolfgang will shut down if the price per piano is less than OA. $3000. B. $4000. O C. $5000. ○ D. None of the above.

Yes, because all 3 firms are producing at their minimum average total cost. OD. The answer is uncertain since it's unknown whether the firms are producing at the minimum efficient scale or not. ○ E.
