Deck 22: Analyzing Mixed Costs

Question 1

Gamach Corporation is a wholesaler that sells a single product.Management has provided the following cost data for two levels of monthly sales volume.The company sells the product for $104.50 per unit. The best estimate of the total monthly fixed cost is:

A) $102,000
B) $518,900
C) $556,800
D) $481,000

Answer 1

A
Explanation:
Variable cost of sales per unit = Change in cost ÷ Change in activity
= ($354,000 - $295,000) ÷ (6,000 units - 5,000 units)
= $59,000 ÷ 1,000 units
= $59.00 per unit
Fixed cost of sales:
Variable selling and administrative cost per unit = Change in cost ÷ Change in activity
= ($202,800 - $186,000) ÷ (6,000 units - 5,000 units)
= $16,800 ÷ 1,000 units
= $16.80 per unit
Fixed cost of sales:
Total fixed cost = $0 + $102,000 = $102,000

Question 2

Larker Brothers,Inc.,used the high-low method to derive its cost formula for electrical power cost.According to the cost formula,the variable cost per unit of activity is $4 per machine-hour.Total electrical power cost at the high level of activity was $19,200 and at the low level of activity was $18,400.If the high level of activity was 3,300 machine hours,then the low level of activity was:

A) 3,100 machine hours
B) 3,200 machine hours
C) 3,000 machine hours
D) 2,900 machine hours

Answer 2

A
Explanation:
Total cost = Total fixed cost + Total variable cost
High level of activity:
$19,200 = Total fixed cost + ($4 per machine-hour × 3,300 machine hours)
Total fixed cost = $19,200 − $13,200 = $6,000
Low level of activity:
$18,400 = $6,000 + ($4 per machine-hour × Low level of activity)
$4 per machine-hour × Low level of activity = $18,400 − $6,000 = $12,400
Low level of activity = 3,100 machine hours.

Question 3

Bakan Corporation has provided the following production and average cost data for two levels of monthly production volume.The company produces a single product. The best estimate of the total variable manufacturing cost per unit is:

A) $126.60
B) $86.30
C) $13.90
D) $112.70

Answer 3

A
Explanation:
Total manufacturing overhead at 4,000 units = 4,000 units × $60.40 per unit = $241,600
Total manufacturing overhead at 3,000 units = 3,000 units × $75.90 per unit = $227,700
Variable manufacturing overhead per unit = Change in cost ÷ Change in activity
= ($241,600 - $227,700) ÷ (4,000 units - 3,000 units)
= $13,900 ÷ 1,000 units
= $13.90 per unit
Total variable manufacturing cost = Direct materials + Direct labor + Variable manufacturing overhead
= $86.30 per unit + $26.40 per unit + $13.90 per unit
= $126.60 per unit

Question 4

Which of the following statements is true when referring to the high-low method of cost analysis?

A) The high-low method has no major weaknesses.
B) The high-low method is very hard to apply.
C) In essence, the high-low method draws a straight line through two data points.
D) The high-low method uses all of the available data to estimate fixed and variable costs.

Question 5

A major advantage of the high-low method of cost estimation is that it omits all data from the analysis other than the lowest and highest costs.

Question 6

In describing the cost formula equation,Y = a + bX,which of the following is correct:

A) "Y" is the independent variable.
B) "a" is the variable cost per unit.
C) "a" and "b" are valid for all levels of activity.
D) in the high-low method, "b" equals the change in cost divided by the change in activity.

Question 7

Managers can use a variety of methods to estimate the fixed and variable components of a mixed cost.In account analysis,an account is classified as either variable or fixed based on the analyst's prior knowledge of how the cost in the account behaves.

Question 8

(The R² (i.e.,R-squared)varies from 0% to 100%,and the lower the percentage,the better the fit of the data to a straight line.

Question 9

The high and low points used in the high-low method tend to be unusual and therefore the cost formula for the mixed cost may not accurately represent all of the data.

Question 10

Edal Corporation has provided the following production and total cost data for two levels of monthly production volume.The company produces a single product. The best estimate of the total variable manufacturing cost per unit is:

A) $63.70
B) $84.40
C) $53.30
D) $20.70

Question 11

The R² (i.e.,R-squared)tells us the percentage of the variation in the dependent variable (cost)that is explained by variation in the independent variable (activity).

Question 12

In a scattergraph of cost and activity,activity is the independent variable because it causes variations in the cost.

Question 13

The highest and lowest costs are always used to analyze a mixed cost under the high-low method.

Question 14

A quick look at a scattergraph of cost versus activity can reveal that there is little relation between the cost and the activity or that the relation is something other than a simple straight line.In such cases,least square regression is highly recommended for estimating fixed and variable costs.

Question 15

The engineering approach to the analysis of mixed costs involves a detailed statistical analysis of cost behavior using methods that minimize the squared errors.
