Question 38 Suppose the market for microwave ovens is perfectly competitive. Also suppose a firm that produces microwave ovens has an average total cost of $200 when selling 200 units. The fixed cost is $100, and the average total cost when selling 201 units is $201. If the market price for a microwave oven is $500, this firm should sell 201 units because its fixed costs are so low. sell 200 units because the marginal cost of the 201st exceeds marginal revenue sell 201 units because it adds to profits. sell 201 units because the marginal cost of the 201st is less than marginal revenue.
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. 200 175 150 125 100 TOTAL COST AND REVENUE (Dollars) 75 50 25 25 ח ☐ -25 0 1 2 ☐ ☐ ?
