  • Where does a perfectly competitive firm find its profit maximizing quantity on a graph?
    A perfectly competitive firm finds its profit maximizing quantity where marginal revenue (MR) equals marginal cost (MC).
  • In perfect competition, what is the relationship between price, average revenue, and marginal revenue?
    In perfect competition, price equals both average revenue (AR) and marginal revenue (MR).
  • How do you calculate profit per unit for a firm?
    Profit per unit is calculated as price minus average total cost (ATC).
  • What is the formula for total profit on the graph?
    Total profit is (Price - ATC) multiplied by the quantity produced.
  • What does it mean if the price is greater than the average total cost at the profit maximizing quantity?
    If price is greater than ATC, the firm makes a profit.
  • What does it mean if the price is less than the average total cost at the profit maximizing quantity?
    If price is less than ATC, the firm incurs a loss.
  • What happens if price equals average total cost at the profit maximizing quantity?
    If price equals ATC, the firm breaks even with no profit or loss.
  • Why might the profit maximizing quantity also be called the loss minimizing quantity?
    Because even if the firm is making a loss, producing where MR = MC ensures the loss is as small as possible.
  • On a graph, how do you identify the profit maximizing quantity?
    You find the intersection point of the marginal revenue and marginal cost curves and drop down to the quantity axis.
  • What area on the graph represents total profit?
    The area between the price line and the ATC curve at the profit maximizing quantity, multiplied by quantity, represents total profit.
  • If a firm cannot produce a fractional unit at the MR=MC point, what should it do?
    The firm should choose the lower whole number quantity to avoid marginal cost exceeding marginal revenue.
  • What is the first step in calculating profit or loss on a graph?
    The first step is to find where marginal revenue equals marginal cost to determine the quantity to produce.
  • How do you find the price to use in profit calculations on the graph?
    The price is found on the demand curve at the profit maximizing quantity.
  • What does the vertical distance between the price and ATC curves at the profit maximizing quantity represent?
    It represents the profit (if price > ATC) or loss (if price < ATC) per unit.
  • Why is the demand curve flat for a perfectly competitive firm?
    The demand curve is flat because the firm is a price taker and can sell any quantity at the market price.
