The Ramirez Company uses standard costing in its manufacturing plant for auto parts. The standard cost of a particular auto part, based on a denominator level of 4,100 output units per year, included 5 machine- hours of variable manufacturing overhead at $ 7 per hour and 5 machine- hours of fixed manufacturing overhead at $ 13 per hour. Actual output produced was 4,500 units. Variable manufacturing overhead incurred was $ 255,000. Fixed manufacturing overhead incurred was $ 385,000. Actual machine- hours were 29,000.

Required

2. Describe how individual fixed manufacturing overhead items are controlled from day to day.

3. Discuss possible causes of the fixed manufacturing overhead variances.
