Janet Dunn, who has just been appointed general manager of the Westwood Plant, has been given instructions to "get things under control." Upon reviewing the plant's income statement, Ms. Dunn has concluded that the major problem lies in the variable cost of goods sold. She has been provided with the following standard cost per swimming pool: Direct materials Direct labor Variable manufacturing overhead Total standard cost per unit Standard Quantity or Hours 3.5 pounds 0.4 hours Standard Price or Standard Rate $ 2.50 per pound $ 6.50 per hour 0.2 hours* $ 2.00 per hour Cost $ 8.75 2.60 0.40 $ 11.75 *Based on machine-hours.
