Question 1 :
Compute the Cost. Edward the entrepreneur takes 2 hours to cut a lawn and he cuts 100 lawns per year. He uses solar-powered equipment (truck and mower) that will last forever -and could be sold at any time for $20,000. Edward could earn $8 per hour as a pedicurist. The interest rate is 10 percent.
a. Given his current output level, his marginal cost is $ __ (enter your response to the nearest dollar) and his average cost is $ __ (enter your response to the nearest dollar).
b. Suppose he decides to reduce the number of lawns cut by half, to 50 per year. His new marginal cost is $ __(enter your response to the nearest dollar) and his new average cost is $ __(enter your response to the nearest dollar).
Question 2 : Compute the Costs. Consider a firm that has a fixed cost of $60.

Question 3. Draw the Long-Run Cost Curve. Consider the long-run production of shirts. The cost of the indivisible inputs used in the production of shirts is $400 per day. To produce 1 shirt per day, the firm must also spend a total of $5 on other inputs-labor, materials, and other capital. For each additional shirt, the firm incurs the same additional cost of $5.
a. The long-run average cost for: 100 shirts is $ , 200 shirts is $ ___, and 400 shirts is ___.
b. Use the 3-point curved line drawing tool to draw the long-run average-cost curve for 100, 200, and 400 shirts per day. Properly label this curve.
Carefully, follow the instructions above, and only draw the required objects.
