Calculators Corporation inadvertently produced 4,000 defective calculators. The calculators cost $5.20 each to be manufactured. A salvage company will purchase the defective units as they are for $7.10 each. The production manager reports that the defects can be corrected for $3.40 per unit, enabling the company to sell them at the regular price of $14.00. The repair operations would not affect other production operations. Prepare an analysis that shows which action should be taken
