firm aims at minimizing its cost. Which of the following statement is TI A. The firm's technology must exhibit decreasing returns-to-scale. B. The average production cost of the firm must increase as y increases. C. The average production cost function may be concave. D. Suppose the firm becomes subject to the short-run constraint that x2 = run total cost curve is always higher than the original long-run total cosi

Question 19 of 20 > (TC is total cost; VC is variable cost; Q is quantity.) ΔΤC . а. b. The amount by which total cost increases when an AQ additional unit is produced: Marginal cost Average (total) cost Average variable cost TC d. The total cost divided by the quantity of output: с. e. The change in total cost divided by the change VC f. in output: g. The sum of all costs that change as output changes divided by the number of units produced:

Joanne sells silk screened T-shirts at community festivals and craft fairs. Her marginal cost to produce one T-shirt is $3.50. Her total cost to produce 70 T-shirts is $305, and she sells them for $7 each a. Find the linear cost function for Joanne's T-shirt production b. How many T-shirts must she produce and sell in order to break even? c. How many T-shirts must she produce and sell to make a profit of $700? a. The linear cost function is C(x)= b. Joanne must produce and sell c. Joanine must produce and sell T-shirts in order to break even, because the number of T-shirts must be a whole number T-shirts to make a profit of $700, because the number of T-shirts must be a whole number

If a firm experiences economies of scale over all relevantlevels of output, its long-run average total cost curve will: O slope downward O slope upward. be vertical O be horizontal.
