Camptown Togs, Inc., a children’s clothing manufacturer, has always found payroll processing to be costly because it must be done by a clerk so that the number of piece-goods coupons received by each employee can be collected and the types of tasks performed by each employee can be calculated. Not long ago, an industrial engineer designed a system that partially automates the process by means of a scanner that reads the piece-goods coupons. Management is enthusiastic about this system because it utilizes some personal computer systems that were purchased recently. It is expected that this new automated system will save $45,000 per year in labor. The new system will cost about $30,000 to build and test prior to operation. It is expected that operating costs, including income taxes, will be about $5,000 per year. The system will have a five-year useful life. The expected net salvage value of the system is estimated to be $3,000.

Explanation:
a) Data and Calculations:
Fixed Variable Actual
Revenue $276 $35,890
Technician wages $8,600 $8,450
Mobile lab operating exp. $4,600 $34 $9,200
Office expenses $2,800 $3 $3,070
Advertising expenses $1,580 $1,650
Insurance $2,890 $2,890
Miscellaneous expenses $930 $1 $375
Expected number of jobs to be worked = 140
Actual number of jobs worked = 150
Flexible costs:
Revenue = $276 * 150 = $41,400
Mobile lab operating expense:
Fixed element = $4,600
Variable element = $34 * 150 = $5,100
Total flexible budget = $9,700
Office Expenses:
Fixed element = $2,800
Variable element = $3 * 150 = $450
Total flexible budget = $3,250
Miscellaneous expenses:
Fixed element = $930
Variable element = $1 * 150 = $150
Total flexible budget = $1,080
Spending Variances:
Technician wages $8,600 $8,450 8,600 150 F
Advertising expenses $1,580 $1,650 1,580 (70) U
Insurance $2,890 $2,890 2,890 0 N/A
