Cover-to-Cover Company is a manufacturer of shelving for books. The company has compiled the following cost data, and wants your help in determining the cost behavior. After reviewing the data, complete requirements (1) and (2) that follow.

Units Produced	Total Lumber Cost	Total Utilities Cost	Total Machine Depreciation Cost
7,000 shelves	$77,000	$10,050	$120,000
14,000 shelves	154,000	18,100	120,000
28,000 shelves	308,000	34,200	120,000
35,000 shelves	385,000	42,250	120,000

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.

Cost	Fixed Portion of Cost	Variable Portion of Cost (per Unit)
Lumber	$fill in the blank e01ef3ff0fc0fd1_4	$fill in the blank e01ef3ff0fc0fd1_5
Utilities	fill in the blank e01ef3ff0fc0fd1_6	fill in the blank e01ef3ff0fc0fd1_7
Depreciation	fill in the blank e01ef3ff0fc0fd1_8	fill in the blank e01ef3ff0fc0fd1_9

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	275		6,250
March	1,000		15,000
April	8,775		133,750
May	1,750		32,500
June	3,015		48,000

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 25f414f5a04df9e_1	$fill in the blank 25f414f5a04df9e_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 25f414f5a04df9e_3
4,360	fill in the blank 25f414f5a04df9e_4
8,775	fill in the blank 25f414f5a04df9e_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.

Review the high-low method, and use the smallest and largest levels of production in your computation.

Sales Mix

Biblio Files Company is making plans for its next fiscal year, and decides to sell two new types of bookshelves, Basic and Deluxe. The company has compiled the following estimates for the new product offerings.

Type of Bookshelf	Sales Price per Unit	Variable Cost per Unit
Basic	$5.00	$1.75
Deluxe	9.00	8.10

The company is interested in determining how many of each type of bookshelf would have to be sold in order to break even. If we think of the Basic and Deluxe products as components of one overall enterprise product called Combined, the unit contribution margin for the Combined product would be $2.31. Fixed costs for the upcoming year are estimated at $344,190. Recall that the totals of all the sales mix percents must be 100%. Determine the amounts to complete the following table.

Type of Bookshelf	Percent of Sales Mix	Break-Even Sales in Units	Break-Even Sales in Dollars
Basic	fill in the blank 06e3b6f83fdffda_1%	fill in the blank 06e3b6f83fdffda_2	$fill in the blank 06e3b6f83fdffda_3
Deluxe	fill in the blank 06e3b6f83fdffda_4%	fill in the blank 06e3b6f83fdffda_5	$fill in the blank 06e3b6f83fdffda_6

Review the definition of break-even point.

Recall that the Combined unit contribution margin is given by [(Basic unit contribution margin) x (Basic percent of sales mix)] + [(Deluxe unit contribution margin) x (Deluxe percent of sales mix)]. Since these percents must add up to 100%, we have the following:

(Basic percent of sales mix) + (Deluxe percent of sales mix) = 100%, so that

(Deluxe percent of sales mix) = 100% - (Basic percent of sales mix)
