Chapter 2 Homework Activity
Sawaya Co., Ltd., of Japan is a manufacturing company whose total factory overhead costs fluctuate considerably from year to yea
according to increases and decreases in the number of direct labor-hours worked in the factory. Total factory overhead costs at high and
low levels of activity for recent years are given below:
Level of Activity
Low High
Direct labor-hours 55,500 74,000
Total factory overhead costs $ 256,400 $ 289,700
The factory overhead costs above consist of indirect materials, rent, and maintenance. The company has analyzed these costs at the
55,500-hour level of activity as follows:
Indirect materials (variable) $ 83,250
Rent (fixed) 127,000
Maintenance (mixed) 46,150
Total factory overhead costs $ 256,400
To have data available for planning, the company wants to
eak down the maintenance cost into its variable and fixed cost elements.
Required:
1. Estimate how much of the $289,700 factory overhead cost at the high level of activity consists of maintenance cost. (Hint: To do this, it
may be helpful to first determine how much of the $289,700 consists of indirect materials and rent. Think about the behavior of variable
and fixed costs!) (Do not round intermediate calculations.)
$Maintenance cost at high level of activity 51,700
2. Using the high-low method, estimate a cost formula for maintenance. (Round the Variable cost per DLH to 2 decimal places.)

Milden Company has an exclusive franchise to purchase a product from the manufacturer and distribute it on the retail level. As an aid in
planning, the company has decided to start using a contribution format income statement. To have data to prepare such a statement, the
company has analyzed its expenses and has developed the following cost formulas:
Cost Cost Formula
Cost of good sold $30 per unit sold
Advertising expense $180,000 per quarte
Sales commissions 7% of sales
Shipping expense ?
Administrative salaries $90,000 per quarte
Insurance expense $10,000 per quarte
Depreciation expense $60,000 per quarte
Management has concluded that shipping expense is a mixed cost, containing both variable and fixed cost elements. Units sold and the
elated shipping expense over the last eight quarters follow:
Quarter Units Sold
Shipping
Expense
Year 1:
First 26,000 $170,000
Second 28,000 $185,000
Third 33,000 $227,000
Fourth 29,000 $190,000
Year 2:

Second 30,000 $195,000
Third 40,400 $242,000
Fourth 37,400 $218,000
Milden Company’s president would like a cost formula derived for shipping expense so that a budgeted contribution format income
statement can be prepared for the next quarter.
Required:
1. Using the high-low method, estimate a cost formula for shipping expense based on the data for the last eight quarters above.
