Exam points

  • complete cost tables using TC = TFC + TVC and ATC = AFC + AVC relationships
  • calculate marginal and average costs from changes in cost, output and per-unit data
  • use MC intersections and relative positions to determine when AVC or ATC rises or falls
  • explain why diminishing marginal product produces an upward-sloping marginal cost curve
  • compare how fixed costs, variable input prices and productivity shift the relevant curves

Question 1

[Maximum number: 2]

The table provided shows the short-run production function for Lowen Feline, a profit-maximizing firm that produces cat food.

Table for Question 1 — AP Microeconomics

Lowen Feline sells as many bags of cat food as it wants at a market price of $ 10 per bag and hires as many workers as it wants at a market wage of $ 18.

Question (a)

(a)
