The incubation period averages 8-12 hours, after which diarrhea and abdominal cramps begin. C. perfringens symptoms usually persist for one day. A severe complication, necrotic enteritis (also known as pig-bel syndrome), can develop if large numbers of bacteria are ingested.
Absorption costing is a costing system which treats all costs of production as product costs, regardless weather they are variable or fixed. The cost of a unit of product under absorption costing method consists of direct materials, direct labor and both variable and fixed overhead.
Under absorption costing, the cost per unit can be calculated as follows: $10 (direct materials) + $8 (direct labor) + $2 (variable manufacturing costs) + $4 ($40,000 per year in fixed manufacturing overhead costs divided by 10,000 units) = $24 per unit. Absorption costing and activity-based costing differ in approach.
