Scenario 13-8 Wanda owns a lemonade stand. She produces lemonade using five inputs: water, sugar, lemons, paper cups, and labor. Her costs per glass are as follows: $0.01 for water, $0.02 for sugar, $0.03 for lemons, $0.02 for cups, and $0.10 for the opportunity cost of her labor.

She earns $10 per hour at a part-time job at the local coffee shop. She can sell a photo frame for $30 each. -Refer to Scenario 13-10. An accountant would calculate the total profit for one photo frame to be

The efficient scale of the firm is the quantity of output that

Suppose that a firm has only one variable input, labor, and firm output is zero when labor is zero. When the firm hires 6 workers it produces 90 units of output. Fixed cost of production are $6 and the variable cost per unit of labor is $10. The marginal product of the seventh unit of labor is 4. Given this information, what is the total cost of production when the firm hires 7 workers?

Table 13-12 Eileen's Elegant Earrings produces pairs of earrings for its mail order catalogue business. Each pair is shipped in a separate box.

Scenario 13-21 Suppose that a small family farm sold its output for $100,000 in a given year. The family spent $25,000 on fuel, $40,000 on seed, fertilizer, and pesticides, and $25,000 on equipment, including maintenance. The family members could have earned $20,000 working at other occupations. -Refer to Scenario 13-21. What is the economic profit for the family farm?

​Chloe's Café sells gourmet cinnamon rolls. In the long run, the café incurs a total cost of $500 to produce 1,000 cinnamon rolls. If Chloe's Café exhibits economies of scale between 1,000 and 2,000 cinnamon rolls, the long-run average total cost for 1,500 cinnamon rolls is
