Answer and Explanation:
The preparation of the responsibility report is presented below:
Particulars Budget Actual difference
Sales $900,660 $888,900 $11,760 F
Variable costs
Cost of goods sold $442,410 $419,540 $22,870 F
Selling and administrative $62,050 $60,800 $1,250 F
Less: total variable costs $504,460 $480,340 $24,120 F
Contribution margin $396,200 $408,560 $12,360 F (A)
Controllable fixed costs
cost of goods sold $101,520 $106,680 $5,160 U
Add or less: Selling and administrative $89,750 $73,180 $16,570 F
Less: total controllable fixed cost $191,270 $179,180 $11,410 F (B)
controllable margin $204,930 $229,380 $23,770 F (A - B)
Now
Return on investment is
= ($229,380 - $89,660) รท $1,169,100
= 11.9%
The favorable variance leads when the standard cost is more than the actual cost while the unfavorable variance leads when the standard cost is less than the actual cost
