Average total cost, sometimes referred to as the per unit total cost, is the per unit cost. This includes fixed costs, those costs that are required for production but do not change based on output, and variable costs, those costs that increase (or decrease) as output increases (or decreases).
The basic stress test involves walking on a treadmill while your electrocardiogram (EKG) is continuously monitored for changes that may indicate a blocked artery to the heart.
