CPA · Question 10 · Area I: Business Analysis

Using the High-Low method, determine the cost formula for maintenance costs based on the following data:<br/>- High Activity: 10,000 machine hours, $55,000 total cost<br/>- Low Activity: 6,000 machine hours, $39,000 total cost<br/><br/>What is the estimated total cost at 8,000 machine hours?

Answer options:

A.

$47,000

B.

$44,000

C.

$48,000

D.

$32,000

How to approach this question

1. Calculate Variable Rate = (Cost at High - Cost at Low) / (Activity at High - Activity at Low). 2. Calculate Fixed Cost = Total Cost - (Rate * Activity). 3. Apply formula to new activity level.

Full Answer

A.$47,000✓ Correct
A
Variable Rate = ($55,000 - $39,000) / (10,000 - 6,000) = $4 per hour.<br/>Fixed Cost = $55,000 - ($4 * 10,000) = $15,000.<br/>Total Cost at 8,000 hours = $15,000 + ($4 * 8,000) = $47,000.

Common mistakes

Selecting high/low based on cost instead of activity; forgetting to add the fixed cost component in the final step.
