74. 75. 76. 77. EXERCISE 23 A delivery service company hires messengers to deliver expensive goods around a wealthy city. Each messenger has a vehicle that he or she brings to the job. Therefore, the only input the company needs to choose is the number of messengers to hire per day. Became the items are expensive and often heavy, it may take several messengers (a team of messengers) to make a single delivery. The market for delivery services in the city is competitive, so the company charges a at-rate com- petitive price per delivery (let P stand for that price). The market for messengers is also competitive, so the company pays its messengers a competitive daily wage (let to stand for the wage]. The number of deliveries per day depends on the number of messengers. Specically, the number of deliveries (y) depends on the number of messengers (it) according to the following function: y = 30-3- Suppose the price for each delivery is $240 and the daily wage paid to each messenger is $48. If the rm wants to maximize prots, how many messengers will it hire per day? Without actually substituting any numbers, you would know that if the price of deliveries (P) in- creases, the optimal number of messengers would a. increase b. decrease c. not change EXERCISE 24 Consider the production function below for a rm producing output (y) using two inputs, (xland 32): y = mn{:r1,2:2}. Let the cost of input in be on, and the cost of input 2:2 be mg. An increase in the unit cost of 2:2, all else being equal, will cause the quantity demanded of 2:1 to a. increase b. decrease (2. remain unchanged An increase in the unit cost of 32, all else being equal, will cause the quantity demanded of 2 to a. increase b. decrease c. remain unchanged Economics 2A Quiz 2, Fall 2021 12 78. An increase in the unit cost of :2, all else being equal, will cause the quantity demanded of y to a. increase b. decrease c. remain unchanged
