  • Where does a perfectly competitive firm maximize profit on a graph?
    A perfectly competitive firm maximizes profit where marginal revenue equals marginal cost.
  • In perfect competition, what is the relationship between price, marginal revenue, and average revenue?
    In perfect competition, price equals both marginal revenue and average revenue.
  • What is the formula for calculating profit for a firm?
    Profit is calculated as (Price - Average Total Cost) × Quantity.
  • What does it mean if price is greater than average total cost at the profit-maximizing quantity?
    If price is greater than average total cost, the firm earns a profit.
  • What happens if price is less than average total cost at the profit-maximizing quantity?
    If price is less than average total cost, the firm incurs a loss but still minimizes that loss by producing where MR = MC.
  • What is the outcome if price equals average total cost at the profit-maximizing quantity?
    If price equals average total cost, the firm breaks even, earning zero economic profit.
  • How do you find the profit-maximizing quantity on a graph?
    Find the quantity where the marginal revenue curve intersects the marginal cost curve.
  • On a graph, how do you determine the price the firm receives for its product in perfect competition?
    The price is found on the demand curve at the profit-maximizing quantity.
  • How do you find the average total cost at the profit-maximizing quantity on a graph?
    Locate the average total cost curve at the profit-maximizing quantity.
  • What does the area between the price and average total cost curves at the profit-maximizing quantity represent?
    It represents the profit (if price > ATC) or loss (if price < ATC) per unit, multiplied by the quantity.
  • If a firm cannot produce a fractional unit at the MR = MC point, what should it do?
    The firm should produce the lower whole number quantity to avoid marginal cost exceeding marginal revenue.
  • Why is the demand curve for a perfectly competitive firm also its marginal revenue curve?
    Because the firm is a price taker, each additional unit sold adds the same amount to total revenue, making demand equal to marginal revenue.
  • What is the significance of the loss-minimizing quantity for a firm?
    It is the quantity where the firm loses the least amount of money, which occurs where MR = MC even if price is below ATC.
  • What are the two main steps to calculate profit or loss on a graph for a perfectly competitive firm?
    First, find where MR = MC to determine quantity; second, use price and ATC at that quantity to calculate profit or loss.
  • What does it mean for a firm to 'break even' in perfect competition?
    Breaking even means total revenue equals total cost, so the firm earns zero economic profit.
