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

QUANTITY (Shirts)
Ginny's profit is maximized when she produces
shirts. When she does this, the marginal cost of the last shirt she produces is $
which is
than the price Ginny receives for each shirt she sells. The marginal cost of producing an additional shirt (that is, one more shirt
than would maximize her profit) is $
, which is
than the price Ginny receives for each shirt she sells. Therefore, Ginny's profit-
maximizing quantity corresponds to the intersection of the
curves. Because Ginny is a price taker, this
last condition can also be written as
