Question

Quizplus · Accepted Answer

The total maintenance cost curve typically starts high due to the costs of breakdown and repairs. As the number of preventive maintenances increase, there is a gradual decrease in breakdown and repair costs. However, there is also an increase in preventive maintenance costs, which eventually causes the total maintenance cost to increase again. Therefore, the curve slopes down initially, but then goes back up as the number of preventive maintenances increase.
