Answer:
The total cost of quality the manager should use to report the costs in the internal failure cost category is $297,000
Step-by-step explanation:
The computation of the internal failure cost is shown below:
= Rework cost + Cost of rejected units
= $257,000 + $40,000
= $297,000
The cost of internal failure includes both the cost of rework and the rejected units.
The other information which is given in the question is not relevant. Hence, ignored it as it would not be considered and thus not taken in the computation part.
