Final answer:
Simple Company's single overhead cost driver rate is $7.62 per direct labor hour, which is calculated by dividing the total overhead of $76,200 by the total direct labor hours of 10,000.
Step-by-step explanation:
To calculate Simple Company's single overhead cost driver rate, we divide the total estimated overhead costs by the total number of direct labor hours. According to the information given, the total overhead is $76,200 and the total direct labor hours are 10,000 hours.
To obtain the overhead rate, we perform the following calculation:
Overhead Rate = Total Overhead / Total Direct Labor Hours
= $76,200 / 10,000 hours
= $7.62 per direct labor hour
Therefore, the overhead rate that Simple Company would use if allocating all overhead based on direct labor hours is $7.62 per direct labor hour.
