Final answer:
The cost of direct labor for the lawyer expressed in dollars per customer is $400.
Step-by-step explanation:
To calculate the cost of direct labor for the lawyer expressed in dollars per customer, we need to find the total cost of labor per customer. First, we need to find the total labor time per customer, which is given as 120 minutes. We can convert this to hours by dividing 120 by 60, which equals 2 hours.
Next, we need to find the total labor cost per customer. The lawyer has a wage rate of $200 per hour, so the total cost of labor per customer is 2 hours multiplied by $200, which equals $400. Therefore, the cost of direct labor for the lawyer expressed in dollars per customer is $400.
