1. Determine whether the costs in the table are variable, fixed, mixed, or none of these.
Variable Cost
Fixed Cost
Mixed Cost
None of these
Lumber
Utilities
Depreciation
2. For each cost, determine the fixed portion of the cost, and the per-unit variable cost. If there is no amount or an amount is zero, enter "0". Recall that, for N= Number of Units Produced, Total Costs = (Variable Cost Per Unit x N) + Fixed Cost. Complete the following table with your answers.
Cost Fixed Portion of Cost Variable Portion of Cost (per Unit)
Lumber $ $
Utilities $ $
Depreciation $ $
Biblio Files Company is the chief competitor of Cover-to-Cover Company in the bookshelf business. Biblio Files is analyzing its manufacturing costs, and has compiled the following data for the first six months of the year. After reviewing the data, answer questions (1) through (3) that follow.

1. From the data previously provided, help Biblio Files Company estimate the fixed and variable portions of its total costs using the High-Low Method. Recall that Total Costs = (Variable Cost Per Unit x Units Produced) + Fixed Cost. Complete the following table.
Total Fixed Cost
Variable Cost per Unit
2. With your Total Fixed Cost and Variable Cost per Unit from the High-Low Method, compute the total cost for the following values of N (Number of Units Produced).
Number of Units Produced
Total Costs
3,500
4,360
5,025
3. Why does the total cost computed for 4,360 units not match the data for January in the table at the top of this panel?
The High-Low method gives a formula for the estimated total cost and may not match levels of production other than the highest and lowest.
The High-Low method only gives accurate data when fixed costs are zero.
The High-Low method gives accurate data only for levels of production outside the relevant range.
The High-Low method is accurate only for months in which production is at full capacity.

----Requirement 1
Variable Cost
Fixed Cost
Mixed Cost
None of these
Lumber
Its all Variable cost because per shelve Lumber cost is always $ 12
Utilities
It’s a mixed cost because total cost is increasing when no. of shelves are increasing but the increase is not at a constant rate
Depreciation
It’s a fixed cost because the total cost is not changing when no. of shelves are increasing
