Rick Company's master budget for the year just completed was based on 100% capacity and included 40,000 machine hours and $240,000 total factory overhead. Budgeted fixed overhead at 75% of factory capacity would be $160,000 (and 30,000 machine hours). The company operated at 90% capacity for the year, and incurred $252,000 total factory overhead cost.

Required: 1. Determine the total overhead flexible budget variance for the year. Show calculations. 2. Calculate the fixed overhead production-volume variance for the year. Show calculations.
