We can see here that the overhead applied to audit services using activity-based costing is $240,300.
To determine the overhead applied to audit services using activity-based costing, we need to calculate the overhead cost per unit of activity for each cost driver.
First, let's calculate the overhead cost per CPU minute:
Overhead cost per CPU minute = Computer support cost / Total CPU minutes
= $267,000 / (40,000 + 10,000)
= $267,000 / 50,000
= $5.34 per CPU minute
Next, let's calculate the overhead cost per legal hour:
Overhead cost per legal hour = Legal support cost / Total legal hours used
= $133,500 / (200 + 800)
= $133,500 / 1,000
= $133.50 per legal hour
Now, we can calculate the total overhead cost for audit services using the respective cost drivers:
Overhead cost for audit services = (Overhead cost per CPU minute × CPU minutes) + (Overhead cost per legal hour × Legal hours used)
= ($5.34 per CPU minute × 40,000 CPU minutes) + ($133.50 per legal hour × 200 legal hours)
= $213,600 + $26,700
= $240,300
Therefore, the overhead applied to audit services using activity-based costing is $240,300.
