Answer:
$23.54
Step-by-step explanation:
Average fixed inspection cost per activity unit is arrived at by dividing the total amount of fixed inspection cost by the activity unit. Activity unit in this case is the total machine hour
6,600 machine-hours = $162,426 total fixed inspection cost
Since Erkkila Inc activity is within the relevant range, at 6,900 machine-hours the same fixed cost will be incurred.
Therefore:
6,900 machine-hours = $162,426 total fixed inspection cost
Average Fixed Inspection Cost Per Activity unit= $162,426/6,900 = $23.54
