Answer:
selling the defective gloves as they are results in a $3,000 higher gain
Step-by-step explanation:
the manufacturing costs of the defective gloves should be considered a sunk cost since they cannot be recovered:
alternative 1, sell defective gloves = $18 x 1,000 = $18,000 gain
alternative 2, repair the gloves and sell them at normal price = ($40 - $25) x 1,000 = $15,000 gain
alternative 1 (selling the defective gloves as they are) results in a $3,000 higher gain
