Suppose Eleanor runs a small business that manufactures teddy bears. Assume that the market for teddy bears is a competitive market, and the
market price is $20 per teddy bear.
The following graph shows Eleanor's total cost curve.
Use the blue points (circle symbol) to plot total revenue and the green points (triangle symbol) to plot profit for teddy bears quantities zero through
seven (inclusive) that Eleanor produces.

Calculate Eleanor's marginal revenue and marginal cost for the first seven teddy bears she produces, and plot them on the following graph. Use the
blue points (circle symbol) to plot marginal revenue and the orange points (square symbol) to plot marginal cost at each quantity.

QUANTITY (Teddy bears)
Eleanor's profit is maximized when she produces
teddy bears. When she does this, the marginal cost of the last teddy bear she produces is
, which is
v than the price Eleanor receives for each teddy bear she sells. The marginal cost of producing an additional teddy
bear (that is, one more teddy bear than would maximize her profit) is S
|, which is
v than the price Eleanor receives for each teddy
bear she sells. Therefore, Eleanor's profit-maximizing quantity corresponds to the intersection of the
v curves. Because Eleanor is a price taker, this last condition can also be written as
COSTS AND REVENUE (Dollars per teddy bear)
