Required
1. Examine the monthly overhead budget to
(a) determine the costs per unit for each variable overhead item and its total per unit costs and (b) identify the total fixed costs per month.
2. Prepare flexible overhead budgets (as in Exhibit 21.12) for December showing the amounts of each variable and fixed cost at the 65%, 75%, and 85% capacity levels.
3. Compute the direct materials cost variance, including its price and quantity variances.
4. Compute the direct labor cost variance, including its rate and efficiency variances.
5.Prepare a detailed overhead variance report (as in Exhibit 21.16) that shows the variances for individual items of overhead.
