Mr. Lorenzo was shocked to see the loss for the month, particularly because sales were exactly as budgeted. He stated, "I sure hope the plant has a standard cost system in operation. If it doesn't, I won't have the slightest idea of where to start looking for the problem." The plant does use a standard cost system, with the following standard variable cost per ingot:

| During October the plant produced 8,000 ingots and incurred the following costs: |
| a. |
Purchased 33,000 pounds of materials at a cost of $2.95 per pound. There were no raw materials in inventory at the beginning of the month.
|
| b. |
Used 27,800 pounds of materials in production. (Finished goods and work in process inventories are insignificant and can be ignored.)
|
| c. |
Worked 3,800 direct labor-hours at a cost of $6.20 per hour. |
| d. |
Incurred a total variable manufacturing overhead cost of $4,560 for the month. A total of 1,900 machine-hours was recorded.
|
| It is the company's policy to close all variances to cost of goods sold on a monthly basis. |

Assume that the company recognizes price variances when materials are purchased. Compute the following variances for October:
|
| a. |
Direct materials price and quantity variances. (Input all amounts as positive values. Leave no cells blank - be certain to enter "0" wherever required. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance.)
