When plotted on a graph, cost functions are usually displayed by having the level of activity (machine hours, etc.) plotted on the vertical axis (called the y-axis ) and the amount of total costs corresponding to (or dependent on) the levels of that activity on the horizontal axis (called the x-axis).

FALSE

Explanation:

Managers should use past data to create a cost function and then use the exact information provided by that cost function to create the budgetary forecast for the next year.

Answer:

FALSE

Explanation:

Managers are interested in estimating past cost-behavior functions because the estimates can help them make more accurate cost predictions, or forecasts, about future costs. But better management decisions, cost predictions, and estimation of cost functions can be achieved only if managers correctly identify the factors that affect costs.

The managers of the production department have decided to use the production levels of 20X2 and 20X4 as examples of the highest and lowest years of operating levels. Data for those years are as follows:

Year Chemicals used Overhead Costs

20X2 140,000 gallons $115,000

20X4 120,000 gallons $100,000

Required:

What is the cost estimating equation for the department if gallons of chemicals are used as the cost driver?

Answer:

Slope (variable cost) = ($115,000 - $100,000) / (140,000 - 120,000) = $0.75

Constant (fixed cost) = $100,000 - $0.75(120,000) = $10,000
