Explanation:

a) Data and Calculations:

Variable costs:                                  Estimates   Flexible    Actual   Variance

Indirect factory wages                      $30,240    $34,117   $32,400   $1,717  F

Power and light                                   20,160    22,745       21,000    1,745  F

Indirect materials                                16,800      18,954      18,250      704  F

Total variable cost                           $67,200    $75,816    $71,650 $4,166  F

Fixed costs:

Supervisory salaries                       $20,000   $20,000  $20,000    $ 0

Depreciation of plant & equipment 36,200     36,200     36,200       0

Insurance and property taxes          15,200      15,200      15,200       0

Total fixed cost                                  71,400      71,400      71,400        0

Total factory overhead cost        $138,600  $147,216  $143,050  $4,166  F

Flexible costs:

Indirect factory wages = $30,240/7,800 * 8,800 = $34,117

Power and light = $20,160/7,800 * 8,800 = $22,745

Indirect materials = $16,800/7,800 * 8,800 = $18,954

Normal capacity = 7,800 hours (100%)

Actual capacity = 8,800 hours (113%)
