Let's assume that a firm produces 60 products. Its total weekly cost (TC) at this output is $2,100. This includes TVC and TFC. We also know that the firm employs 3 part- time workers at a wage cost of $600 per worker per week. This is the firm's only variable cost (TVC). What is the firm's average fixed cost (AFC) at this output? O $2.50. O $2. O $5. O $100. O $10. Let's assume that a firm's total weekly costs are as follows: 1. Salaries of hired workers $5,000. 2. Supplies = $1,000. 3. Rent = $600, 4. The owners have invested a certain amount of their own money into the business. This could have earned them interest of $200 per week if they had chosen to put it into a bank instead of investing it into their business. 5. The value of the owner's time is estimated to be $800 per week. What are the firm's total economic costs? O $6.000 O $7.600. O $900. $7.500. O $6.700.
A firm has a fixed production cost of $1,000 and a constant marginal cost of production of $700 per unit produced. What is the firm's total cost function? O A. TC = 1,000 + (700q) O B. TC = 1,000 + (700q). OC. TC = 700q. O D. TC = 1,000. The firm's average total cost (ATC) of production is O A. ATC = 1,000 + (700q). OB. 1,000 + (700q) ATC = Oc. 1,000 ATC = O D. ATC = 700q. O E. ATC = 700. If the firm wanted to minimize the average total cost, would it choose to be very large or very small? Explain. OA. very small because the average total cost of production rises with output. O B.- very large because the average variable cost of production falls with output. OC. very small because the average fixed cost of production rises with output. O D. very small because the total cost of production rises with output. O E. very large because the average total cost of production falls with output.

Consider the same firm from the Monday assignment but now let's call that cost schedule total variable cost. Q 1 2 3 4 5 6 7 8 9 TVC 12 20 24 28 34 42 52 64 78 And let's imagine that there is fixed costs of 18 which is sunk in the short run. a. Show this firm's average total cost, average variable cost and marginal cost on a graph. Indicate the efficient scale (I don't think the book uses the words "efficient scale" but it's the quantity where profit would be zero when P=MC. We will discuss what I mean by "efficient scale but probably not before Thursday. By "indicate" I mean give the quantity and MC. I don't need every point to be exactly to scale, I just care about the general shape of the curves, where things cross and the location and…
Suppose you are given the following table (note: labor is the only variable input and all workers are paid equally): Labor Quantity Fixed Costs Variable Costs Total Costs 0 units $10 0 1 2 3 10 units 18 units 20 units $50 What is the value of this company's fixed costs? O a. $0 O b. $10 O C. $20 O d. $30 O e. $50
a) Complete the following table by filling in the fixed cost (FC), variable cost (VC), total cost (TC) and marginal cost (MC) columns. b) For what levels of output is the marginal cost decreasing? For what levels of output is it increasing? What is the level of output at which marginal cost equals average cost? c. Why do we assume that marginal cost first decreases then increases?
