Variable Costs - Managerial Accounting

The video tutorial explains variable costs, highlighting that total costs vary with activity levels while per unit costs remain constant. An example using wedding catering illustrates how costs change with the number of attendees. The tutorial also describes how variable costs can be represented graphically, with total cost on the Y-axis and quantity on the X-axis, forming a diagonal line whose slope depends on the variable cost.

What remains constant regardless of the level of activity?

• Total revenue

• Number of units

• Cost per unit

• Total cost

In the wedding example, if the cost per plate is $12 and 150 people attend, what is the total cost?

• $2400

• $1200

• $1500

• $1800

Why is catering considered a variable cost in the wedding example?

• It is a fixed cost per event

• It is a one-time cost

• It varies with the number of guests

• It is independent of the number of guests

On a graph representing variable costs, what does the Y-axis typically represent?

• Fixed cost

• Variable cost per unit

• Total cost

• Total quantity

What determines the slope of the line in a graph of variable costs?

• The total cost

• The fixed cost

• The total quantity

• The variable cost per unit
