B. At what output (Q) level is profit maximized? Profit is maximized at a level of 4 outputs which the profits is at its highest of $500 where MR >MC.
C. At what output (Q) level is revenue maximized? The revenue is maximized at 6 outputs which the revue is $660.
D. Discuss any differences in your answers to parts B and C. The difference is that in question (a) the profit is maximized at a level of 4 outputs where the marginal revenue is greater than the marginal cost which means the business is making money. In comparison to question (b) the revenue is maximized at a level of 6 outputs to $660 but the marginal cost is greater than the marginal revenue which means the business is loosing money on every product they produce.
2. Use the following information on a hypothetical short-run production function to answer questions a-c.
Units of Labor/Day 5 6 7 8 9
Units of Output/Day 120 140 155 165 168
The price of labor is $20 per day. Ten units of capital are used each day, regardless of output level. The price of capital is $50 per unit.
