$1.$ Determine whether the costs in the table are variable, fixed, mixed, or none of these.

Lumber

Variable Cost

Utilities

Mixed Cost

Depreciation

Fixed Cost

$2.$ 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. Round variable portion of cost $($per unit$)$ answers to two decimal places.

Review the definitions for fixed, variable, and mixed costs, and the relationships between units produced and total cost for each type of cost$.$ Recall that the high$-$low method may be used to separate a cost into its fixed and variable components.

High$-$Low

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.

Units Produced Total Cost

January $4,360$ units $$65,600$

February $2756,250$

March $1,00015,000$

April $6,775103,750$

May $1,75032,500$

June $3,01548,000$

$1.$ 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 Number of Units Produced$)+$ Fixed Cost. Complete the following table.

Total Fixed Cost Variable Cost per Unit

$fill in the blank $0$ad$4$a$70$b$5033$fe$2\_2$

$2.$ 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 Cost

$3,500$ $fill in the blank $0$ad$4$a$70$b$5033$fe$2\_3$

$4,360$ fill in the blank $0$ad$4$a$70$b$5033$fe$2\_4$

$6,775$ fill in the blank $0$ad$4$a$70$b$5033$fe$2\_5$

$3.$ Why does the total cost computed for $4,360$ units not match the data for January?

a$.$ The high$-$low method is accurate only for months in which production is at full capacity.

b$.$ The high$-$low method only gives accurate data when fixed costs are zero.

c$.$ 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.

d$.$ The high$-$low method gives accurate data only for levels of production outside the relevant range.
