Work through these flashcards in short sessions. Try to answer each prompt before flipping the card, then revisit any cards you miss until the explanation feels automatic.

Flashcard 1: Identify the profit-maximizing output level.

Answer: Output where MR = MC. Profit maximized where additional revenue equals additional cost.

Flashcard 2: Identify the condition for profit maximization in perfect competition.

Answer: MR = MC. Marginal revenue equals marginal cost at profit maximum.

Flashcard 3: What is the definition of total cost?

Answer: Sum of total fixed cost and total variable cost. Total cost equals fixed plus variable costs.

Flashcard 4: What is normal profit?

Answer: Total Revenue = Total Cost including opportunity costs. Zero economic profit after accounting for opportunity costs.

Flashcard 5: Identify the condition for zero economic profit.

Answer: TR = TC including opportunity costs. Revenue equals all costs including opportunity costs.
