Goldencoast Industries uses standard costing and a flexible budget for cost plan- ning and control. Its monthly budget for overhead costs is $100,000 of fixed costs plus $5 per machine hour. Monthly normal capacity of 100,000 machine hours is used to compute the standard fixed overhead rate. During the month, 104,000 machine hours were used. Only 102,500 standard machine hours were allowed for good units produced during the month. Actual overhead costs incurred during the month totaled $511,000 of variable costs and $94,500 of fixed costs.
