Suppose there are 1000 firms in a market and all are identical. Firm A will hire 20 workers when the wage rate is $10, 25 workers when the wage rate is $9, and 30 workers when the wage rate is $8. The equilibrium wage rate for a number of years has been $9. If the wage rate falls to $8, we know that

Suppose there are three types of consumers who attend concerts at your university’s performing arts center: students, staff, and faculty. each of these groups has a different willingness to pay for tickets; within each group, willingness to pay is identical. there is a fixed cost of $1,000 to put on a concert, but there are essentially no variable costs. for each concert: i. there are 140 students willing to pay $20. (ii) there are 200 staff members willing to pay $35. (iii) there are 100 faculty members willing to pay $50. a) if the performing arts center can charge only one price, what price should it charge? what are profits at this price? b) if the performing arts center can price discriminate and charge two prices, one for students and another for faculty/staff, what are its profits? c) if the performing arts center can perfectly price discriminate and charge students, staff, and faculty three separate prices, what are its profits?

Which of the following would not generally be a motive for a firm to hold inventories? a. to decouple or separate parts of the production process b. to provide a stock of goods that will provide a selection for customers c. to take advantage of quantity discounts d. to minimize holding costs e. all of the above are functions of inventory.

Ahospital purchases a $500,000 magnetic resonance imaging (mri) machine that has a useful life of 9 years. the salvage value at the end of 9 years is $77,000. (a) write a linear equation that describes the value y (in dollars) of the mri machine in terms of the time t (in years), 0 ≤ t ≤ 9. (b) find the value, in dollars, of the machine after 6 years. $ (c) find the time, in years, when the value of the equipment will be $140,000. (round your answer to two decimal places.) yr
