P13-5 Direct materials and direct labor, variance analysis; factory overhead cost variance analysis Route 66 Tire Co. manufactures automobile tires. Standard costs and actual costs for direct materials, direct labor, and factory overhead incurred for the manufacture of 10,000 tires were as follows: Standard Costs Direct materials Direct labor Factory overhead Actual Costs 83,800 lbs. at $6.17 4,450 hrs. at $21.00 85,000 lbs. at $6.25 4,000 hrs. at $20.80 Rates per direct labor hr., based on 100% of normal capacity of 5,000 direct labor hrs.: Variable cost, $2.90 Fixed cost, $11.40 $11,375 variable cost $57,000 fixed cost Instructions Determine (a) the price variance, quantity variance, and total direct materials cost variance; (b) the rate variance, time variance, and total direct labor cost variance; and (c) Appendix: variable factory overhead controllable variance, the fixed factory overhead volume variance, and total factory overhead cost variance
