3. Profit maximization using total cost and total revenue curves
Suppose Jayden operates a handicraft pop-up retail shop that sells rompers. Assume a perfectly competitive market structure for rompers with a
market price equal to $20 per romper.
The following graph shows Jayden's total cost curve.
Use the blue points (circle symbol) to plot total revenue and the green points (triangle symbol) to plot profit for rompers for quantities zero through
seven (including zero and seven) that Jayden produces.

Audra runs a movie memorabilia website. Last year, she earned $35,000 in revenue and had explicit costs of $8,000. Audra could have made $35,000 working for a security company and received an additional $7,500 if she had used the company's inputs in a different way. Calculate Audra’s economic profit.
