Excess of actual cost over standard cost per unit | $ | 0.34 | ||||
The production superintendent was pleased when he saw this report and commented: “This $0.34 excess cost is well within the 2 percent limit management has set for acceptable variances. It's obvious that there's not much to worry about with this product." |
Actual production for the month was 12,000 units. Variable overhead cost is assigned to products on the basis of direct labor-hours. There were no beginning or ending inventories of materials. |
Required: |
1. | Compute the following variances for May: |
a. |
Materials price and quantity variances. (Input all amounts as positive values. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e, zero variance).) |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
3. |
How much of the $0.34 excess unit cost is traceable to apparent inefficient use of labor time? (Input all values as positive amounts. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Do not round intermediate calculations. Round your final answers to 2 decimal places.)
