1.The difference between actual overhead costs incurred and the budgeted overhead costs based on a flexible budget is the:

Production variance.Quantity variance.Volume variance.Price variance.Controllable variance.

2.Regarding overhead costs, as volume increases: Unit fixed cost increases, unit variable cost decreases. Unit fixed cost decreases, unit variable cost increases. Unit variable cost decreases, unit fixed cost remains constant. Unit fixed cost decreases, unit variable cost remains constant. Both unit fixed cost and unit variable cost remain constant.
