drug. Exercise 2 (Material Variances) Jasper Household Products, Inc., manufactures a number of consumer items for general household use. One of these products, a chopping board, requires an expensive hardwood. During a recent month, the company manufactured 4,000 chopping boards using 11,000 board feet of hardwood. The hardwood cost the company P18,700. The company's standards for one chopping board are 2.5 board feet of hardwood, at a cost of P1.80 per board foot. W Required: Standard Costs and Operating Performance Measures 347 1. What cost for wood should have been incurred to make 4,000 chopping blocks? How much greater or less is this than the cost that was incurred? 2. Break down the difference computed in (1) above into a materials price variance and a materials quantity variance. Exercise 3 (Labor and Variable Overhead Variances) Halliwell Audio, Inc., manufactures military-specification compact discs. The company uses standards to control its costs. The labor standards that have been set for one disc are as follows: Standard Hours 24 minutes Standard Rate per Hour P6.00 Standard Cost P2.40 During July, 8,500 hours of direct labor time were recorded to make 20,000 discs. The direct labor cost totaled P49,300 for the month. Required: 1. What direct labor cost should have been incurred to make the 20,000 discs? By how much does this differ from the cost that was incurred? 2. Break down the difference in cost from (1) above into a labor rate variance and a labor efficiency variance. 3. The budgeted variable manufacturing overhead rate is P4 per direct labor-hour. During July, the company incurred P39,100 in variable manufacturing overhead cost. Compute the variable overhead spending and efficiency variances for the month
