7. Suppose the firm can choose whatever combination of capital (K) and labor (L) it wants to produce 600 units. Suppose the price of capital is $1,000 per machine per week. What combination of inputs (K and L) will the firm use if the weekly salary of each worker is $400?

GM cuts jobs at its Australian manufacturing unit GM will cut 500 jobs, or about 12% of its workforce, at its Australian plant because of a sharp fall in demand for its locally-made "Cruze" small car. Source: The Wall Street Journal, April 8, 2013 As GM cuts its workforce, how will the marginal product and average product of a worker change in the short run? Suppose that before the cuts the marginal product of GM workers is below their average product. As the number of workers decreases, the marginal product of a GM worker and the average product of a GM worker in the short run. increases; decreases does not change; does not change decreases; decreases increases; increases decreases; increases

1. Suppose the production function is Q = 8L + 15K where Q is the quantity of output, L is the quantity of labor used in production, and K is the quantity of capital used in production. What can be said about this production function? It has Decreasing Returns to Scale It has Constant Returns to Scale It has Increasing Returns to Scale There isn’t enough information to determine the Returns to Scale for this production function   2. You’re dreaming of what to do during a nice summer day. You could mow the lawn which you would pay someone $15 to do for you. You could go for a walk which you value at $11. You could also take a nap and ignore everyone and everything else which you would pay $29 to do. If you to take a nap, what is your opportunity cost? Group of answer choices $29 $26 $15 $11

Q3) A chair manufacturer hires its assembly-line labor for $30 an hour and calculates that the rental cost of its machinery is $15 per hour. Suppose that a chair can be produced using 4 hours of labor or machinery in any combination. Graphically illustrate the isoquant and the two isocost lines for the current combination of labor and capital and for the optimal combination of labor and capital.
