Direct Materials, Direct Labor, and Factory Overhead CostVariance Analysis
Mackinaw Inc. processes a base chemical into plastic. Standardcosts and actual costs for direct materials, direct labor, andfactory overhead incurred for the manufacture of 6,800 units ofproduct were as follows:
| Standard Costs | Actual Costs |
Direct materials | 8,800 lb. at $5.60 | 8,700 lb. at $5.40 |
Direct labor | 1,700 hrs. at $17.30 | 1,740 hrs. at $17.70 |
Factory overhead | Rates per direct labor hr., | |
| based on 100% of normal | |
| capacity of 1,770 direct | |
| labor hrs.: | |
| | Variable cost, $3.10 | $5,220 variable cost |
| | Fixed cost, $4.90 | $8,673 fixed cost |
Each unit requires 0.25 hour of direct labor.
Required:
a. Determine the direct materials pricevariance, direct materials quantity variance, and total directmaterials cost variance. Enter a favorable variance as a negativenumber using a minus sign and an unfavorable variance as a positivenumber.

PART 2
Leno Manufacturing Company prepared the following factoryoverhead cost budget for the Press Department for October of thecurrent year, during which it expected to require 18,000 hours ofproductive capacity in the department:
Variable overhead cost: | | |
Indirect factory labor | $169,200 | |
Power and light | 8,100 | |
Indirect materials | 43,200 | |
Total variable overheadcost | | $220,500 |
Fixed overhead cost: | | |
Supervisory salaries | $77,180 | |
Depreciation of plant and equipment | 48,510 | |
Insurance and property taxes | 30,870 | |
Total fixed overheadcost | | 156,560 |
Total factory overhead cost | | $377,060 |
Assuming that the estimated costs for November are the same asfor October, prepare a flexible factory overhead cost budget forthe Press Department for November for 16,000, 18,000, and 20,000hours of production. Round your interim computations to the nearestcent, if required. Enter all amounts as positive numbers.
