Pepper Corp. makes and sells a product that normally sells for $28. Because of a defective machine, 1,000 units were not produced correctly and remain in inventory. Each of the defective unit has the following costs assigned to it by the company's absorption costing system:

Direct materials	$5.00 per unit
Direct labor	$3.00 per unit
Variable Overhead	$0.5 per unit
Fixed Overhead	$0.75 per unit

The company has two options regarding the defective units: (1) be sold for $8 per unit, or (2) repaired and sold at the regular price.

Q.) What is the maximum cost of repair per unit in order for the company to choose option (2)?
