Chapter 16 - Cost Concepts Quiz

Which of the following is considered a fixed cost?

• Raw material costs

• Factory rent

• Direct labor costs

Answer explanation

Factory rent is a fixed cost because it does not change with production levels, unlike raw material and direct labor costs, which vary based on output.

Fixed costs remain:

• The same regardless of production level

• Directly proportional to output

• Variable with changes in sales

Answer explanation

Fixed costs are expenses that do not change with the level of production or sales. Therefore, they remain the same regardless of production level, making the correct choice "The same regardless of production level."

An example of a fixed cost for a business is:

• Cost of raw materials

• Electricity cost per unit produced

• Lease payments on machinery

Answer explanation

Lease payments on machinery are a fixed cost because they do not change with the level of production. In contrast, costs like raw materials and electricity vary with production volume.

Variable costs:

• Do not change with production levels

• Change in proportion to the level of output

• Are unaffected by sales volume

Answer explanation

Variable costs change in proportion to the level of output, meaning as production increases or decreases, these costs will also rise or fall accordingly. This distinguishes them from fixed costs, which remain constant.

Which of the following is typically a variable cost?

• Factory rent

• Salaries of managers

• Direct materials

Answer explanation

Direct materials are costs that vary with production levels, making them a variable cost. In contrast, factory rent and salaries of managers are fixed costs, remaining constant regardless of production volume.

As production increases, variable costs:

• Decrease

• Remain constant

• Increase in total

Answer explanation

As production increases, variable costs, which depend on the level of output, will increase in total. This is because more resources are needed to produce additional units, leading to higher overall variable costs.

Total cost is the sum of:

• Fixed costs and sales revenue

• Fixed costs and variable costs

• Sales revenue and profit

Answer explanation

Total cost is calculated by adding fixed costs, which do not change with production levels, to variable costs, which fluctuate with output. Therefore, the correct answer is fixed costs and variable costs.

If a company has high fixed and low variable costs, its total cost will:

• Increase slowly as output increases

• Decrease with higher output

• Remain the same regardless of output

Answer explanation

A company with high fixed and low variable costs will see its total cost increase slowly as output increases, since fixed costs remain constant while variable costs add only a small amount to total costs.

To calculate total cost, you add:

• Selling price to total sales

• Fixed costs and variable costs

• Fixed costs and profit

Answer explanation

To calculate total cost, you need to sum fixed costs (overhead) and variable costs (costs that vary with production). This gives you the total expenses incurred, which is essential for understanding overall costs.

Average cost is calculated by dividing total cost by:

• Total output

• Total fixed costs

• Total revenue

Answer explanation

Average cost is calculated by dividing total cost by total output. This gives the cost per unit produced, making 'Total output' the correct choice. The other options do not relate to average cost calculation.
