A firm that produces with only capital and labor makes 10,000 units and sells them for $4 each. It pays its capital $0.50 per hour and uses 2000 units; it pays its labor $20 per hour and uses 400 units. Assuming this is the only relevant information, calculate this firm's profit, carefully following all numeric instructions. We'll use this information again in the next question. D Question 6 3 pts Recall the last question: A firm that produces with only capital and labor makes 10,000 units and sells them for $4 each. It pays its capital $0.50 per hour and uses 2000 units; it pays its labor $20 per hour and uses 400 units. Now let's add some extra info: The price level in the economy where this firm operates is currently $4. If the firm is maximizing profits, the marginal product of labor at the current production level must be units. (Carefully follow all numeric directions.)
