Assignment:
In this Assignment, you will define and calculate the remaining six major cost elements of a business, when given the Total Costs and the Quantity Produced, as well as to use the computed costs to determine a minimum cost output level for that business. In addition, you will also clearly explain how the Average Total Cost of a new output level is affected by its share of Fixed Costs and Variable Costs.
Questions
1. When Total Costs (TC) are known, explain how to calculate each of the following:
a. Fixed Costs (FC)
b. Variable Costs (VC)
c. Average Variable Costs (AVC)
d. Average Total Costs (ATC)
e. Average Fixed Costs (AFC)
f. Marginal Costs (MC)
2. Table. shows the hourly production and Total Cost estimates for a new manufacturing firm wishing to enter the smart phone market. Fill in the blank cells in columns a., b., c., d., and e. on the table by computing the appropriate values.

3. Based on your calculations in completing the table in Question 2, what is this manufacturer's minimum cost output level? Explain your answer.
4. According to our textbook (page 341) when one additional unit is produced, two factors directly impact the change in average total costs, the Spreading effect and the Diminishing Returns effect. In the following two situations explain how the factors of the Spreading effect and the Diminishing Returns effect cause the average total cost to be different.
a. Production of the 10th Gizmo resulted in an average total cost (ATC) of $20, but production of the 11th Gizmo resulted in an average total cost of $22.
b. Production of the 10th Gizmo resulted in an average total cost (ATC) of $20, but production of the 11th Gizmo resulted in an average total cost of $18.
DISCUSSION
Topic: Increase in Fixed Costs
1. Suppose a business experiences a sudden increase in its fixed costs. For example, suppose property taxes increase dramatically. What impact, if any, will this have on the following:
a. the firm's AFC (average fixed cost);
b. the firm's AVC (average variable cost);
c. the firm's ATC (average total cost); and,
d. the firm's MC (marginal cost)?
What changes, if any, is there likely to be in these same cost CURVES?
