ABC Company would like to purchase a  particular item from a potential supplier. ABC does not know the  supplier's specific cost structure for producing this item, but hope to  estimate the cost using some information gathered from the supplier.  After a couple of meetings with the supplier, ABC is able to gather the  following information.
 
 If the purchase price is $12, the supplier requires at least 6,000 units to avoid a loss (break-even).
 If the purchase price is $15, the supplier requires at least 4,000 units to avoid a loss (break-even).
 The supplier's SGA expense (selling, general, administrative) is estimated to be $1.5 per unit.
 The supplier's direct material cost is estimated to be $2 per unit.
 The supplier's material to labor ratio is estimated to be 1.25.
 
 ABC finally agrees to pay $12 per unit and anticipates a volume of 8,000  in the upcoming year.  Based on the information above, answer the  following questions.
 
 1. Using the break-even analysis technique, identify the supplier's  fixed and variable cost for producing this item. (Assuming the variable  cost increases linearly with the purchase volume)
 
 2. What is the unit production cost for the supplier?  If the supplier  uses the cost markup pricing model for pricing, what is the markup (in  terms of percentage)?  What is the profit margin rate (in terms of  percentage) if the supplier uses the margin pricing model?
 
 3. Assuming the supplier's production cost for this item only consists  of SGA, direct material, direct labor, and overhead, identify the cost  per unit each of the components contributes.
 
 4. Assuming the SGA expense is fixed cost, and material and labor costs  are variable costs, what percentage of the overhead cost are variable?
