A cost that is $28.00 per unit when production is 70,000, and $17.50 per unit when production is 112,000. A cost that is $28.00 per unit when production is 70,000, and $56.00 per unit when production is 112,000. A cost that is $56.00 per unit when production is 70,000, and $56.00 per unit when production is 112,000
