The variable cost (related to the production volume) will be 10.7 in total per week (100 units)
100 units x 16 dollar total unit cost = 1600
the total cost is composed of both, variable and fixed costs so we have to subtract the fixed cost to arrive at the variable cost.
total cost = fixed + varible
total - fixed = variable
1600 - 530 = 1070
The variable cost is 1070 in total
while: 1070/ 100 = 10.7 per unit.
Variable costs are costs that change as the quantity changes. Examples of variable costs include raw materials, parts labor, production materials, handling charges, shipping charges, packaging materials, and credit card fees. In some accounting documents, variable costs are called "cost of goods sold."
