Answer:
The cost of direct labor for the lawyer based on demand rate = $750 per customer
Cost of direct labour for the lawyer based on supply rate = $450 per customer
Step-by-step explanation:
Cost of direct labour is normally calculated from the demand rate.
In a 10 hour work period, the lawyer has 3 customers.
In a 10 hour work period, the lawyer is paid $225 × 10 = $2250
Wage rate per customer = ($2250/3) = $750 per customer
Based on supply rate (Rate at which the lawyer answers the customers)
Lawyer spends 117 minutes per customer. That is, (117/60) = 1.95 hours per customer.
Meaning, in a 10 hour work period, the lawyer has (10/1.95) = 5.13 ≈ 5 customers per 10 hour work day.
Direct labour rate based on the supply rate = $2250/5 = $450 per customer.
