Answer:
Always increases with output.
Step-by-step explanation:
Total variable cost refers to the cost of producing the output and it changes with any change in the level of output. If the production volume of a particular firm increases then as a result the total variable cost also increases and if the production volume decreases then the total variable cost also decreases. It is a part of total cost.
Total cost = Total fixed cost + Total variable cost
Total variable cost is determined by multiplying the number of units produced with the variable cost per unit.
