A dinosaur sells for $27 and uses $10 worth of raw materials. Each dinosaur that is manufactured increases the company’s variable labor and overhead costs by $14. A tractor sells for $21 and uses $9 worth of raw materials. Each tractor built increases the company’s variable labor and overhead costs by $10.
