Explanation:
Absorption costing classifies cost into production and non-production cost. Non production costs include selling and administrative cost
Production cost also known as manufacturing cost is the addition of Direct material + Direct labour and Manufacturing overheard
Production cost for Santana Company =
250,000 + 120,000 + 60,000 + 20,000 = $ 450,000.00
Product cost per unit = Total production cost / Number of units
                  = $450,000/ 40,000 units
                 =  $11.25
Product cost per unit  =  $11.25
