Final answer:
To calculate the total variable cost at an activity level of 8,900 units, divide the total variable cost at the given activity level by the activity level. To calculate the total cost, add the total fixed cost to the total variable cost. The average variable cost per unit is obtained by dividing the total variable cost by the activity level. The average fixed cost per unit is obtained by dividing the total fixed cost by the activity level. The average total cost per unit is obtained by dividing the total cost by the activity level.
Step-by-step explanation:
To calculate the total variable cost at an activity level of 8,900 units, we use the formula:
Total Variable Cost = Variable Cost per Unit x Activity Level
We can obtain the variable cost per unit by dividing the total variable cost at the given activity level by the activity level:
Variable Cost per Unit = Total Variable Cost / Activity Level
To calculate the total cost, we add the total fixed cost to the total variable cost:
Total Cost = Total Fixed Cost + Total Variable Cost
The average variable cost per unit is obtained by dividing the total variable cost by the activity level:
Average Variable Cost per Unit = Total Variable Cost / Activity Level
The average fixed cost per unit is obtained by dividing the total fixed cost by the activity level:
Average Fixed Cost per Unit = Total Fixed Cost / Activity Level
The average total cost per unit is obtained by dividing the total cost by the activity level:
Average Total Cost per Unit = Total Cost / Activity Level
