technical efficiency.
optimal engineering.
economic efficiency.
average-cost production.

Question 3
The Southern Tree Trimming Corporation reported an accounting profit of $35,000 and a normal rate of return of 15 percent on capital and enterprise of $30,000. The opportunity cost of labor is $15,500. What is the economic profit?

total monetary costs.
total implicit costs.

Question 5

the plant size to go with the fixed quantity of labor.
the desired quantity of labor to go with fixed capital.
the desired long-run MC curve.
the desired short-run AC curve.
the desired long-run AC curve.

Question 6
Last spring, Coil Spring Co. reported that average fixed costs had increased, but average variable costs were unchanged. This indicates that
marginal costs are less than average variable cost but greater than average cost.
fixed costs have increased.
output is declining.
marginal costs have increased.

Question 7
Technical efficiency is
using the least-cost method of production.
the method of production that minimizes physical usage of inputs according to some specific rule.
the process of turning inputs into outputs.
the process of minimizing output with a given level of inputs.
the method of production that uses the least labor per unit of capital.
