Cost

function

Explanation

Maintenance

Mixed

The cost neither remains constant in total nor remains constant per unit.

Health insurance

Fixed

Although the cost driver varies from month to month, the total cost remains constant.

Shipping costs

Variable

The cost per unit remains constant each month.

Requirement 1. Which of the preceding costs is​ variable? Fixed?​ Mixed? Explain.

Requirement 2. Using the​ high-low method, determine the cost function for each cost.

Begin by selecting the general formula that represents the linear cost function for each cost.

Maintenance

y = a + bX

Health insurance

y = a

Shipping costs

y = bX

Now determine the cost function for each cost. ​(Enter all values in the same format as the general linear formula. If a box is not used in the​ equation, leave the box​ empty; do not enter a zero or select a​ label.)

2. Using the​ high-low method, determine the cost function for each cost.1. Which of the preceding costs is​ variable? Fixed?​ Mixed? Explain.

3. Combine the preceding information to get a monthly operating cost function for the Silk Corporation.

4.Next​ month, Silk expects to use 470 machine​ hours, have 140 employees, and ship 8,900 units. Estimate the total operating cost for the month.

5. This question is continued, Can you help me with the rest. Requirement 3. Combine the preceding information to get a monthly operating cost function for the Silk Corporation. Monthly operating = 1)______ + 2) ______ 3)________ + 4)_______ 5)________ 3) & 4) are a multiple choice. These are the options : per employee, or per machine hours or per units shipped.

1.

Cost Function Explanation
Maintenance Mixed The cost neither remains constant in total nor remains constant per unit
Health insurance Fixed Although the cost driver varies from month to month, the total cost remains constant
Shipping costs Variable The cost per unit remains constant each month.

2.

Maintenance :

Variable cost per machine hour = $5,226 - 4,375 / 483 - 125 = $2.377 per machine hour

Fixed cost = $5,226 - (483*$2.377) = $4,078

Health insurance:

y = $8,560

Shipping cost:

Variable cost per units shipped = $22,784 / 7,120 = $3.2 per unit shipped

Cost Function:
Maintenance y = $4,078 + $2.377 per machine hour
Health insurance y = $8,560
Shipping cost y = + $3.2 per units shipped

3.

Monthly operating cost function = $12,638 + $3.2 per units shipped + $2.377 per machine hour

4.

Total operating cost for next month = $12,638+$3.2*8,900+$2.377*470

Total operating cost for next month = $12,638+28,480+1,117 = $42,235
