A business owner makes 50 items by hand in 40 hours. She could have earned $20 an hour working for someone else. Her total explicit costs are $200. If each item she makes sells for $15, her economic profit equals?

-250: Economic profit = total revenue- economic costs total revenue= 750 (15*50) economic costs= implicit+explicit explicit = 200 implicit = 800 (20*40) economic costs = 1000 (200 +800) economic profit = TR (750)- EC (1000)= -250

A young Thomas Edison produces and sells 20 light bulbs a week in his dorm room. The parts for each light bulb cost $2.00. He sells each light bulb for $5.00. General Electric offers Thomas an executive job that pays $50.00 a week. Thomas's weekly economic profit from making light bulbs is equal to:

10; Economic Profit=total revenue- economic costs total revenue=100; (20*5) economic costs=implicit+explicit implicit= 50 explicit = 40 (2*40) Economic costs= 90 (50+40) Economic profit= TR (100)- EC (90)= 10

Suppose that a firm produces 200,000 units a year and sells them all for $10 each. The explicit costs of production are $1,500,000 and the implicit costs of production are $300,000. The firm earns an accounting profit of ________ and an economic profit of ________.

500,000, 200,000 TR= 200,000*10= 2,000,000 Accounting = TR- explicit (2,000,000- $1,500,000= 500,000) Economic profit = TR - economic cost (explicit + implicit. 2,000,000- ($1,500,000 + $300,000)= 200,000

Assume that in the short run a firm is producing 100 units of output, has average total costs of $200, and has average variable costs of $150. The firm's total fixed costs are Multiple Choice A/ $5,000. B. $500. C. $0.50. D. $50.
