|
Mr. Santiago 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: |
