Answer:

B.0.3125

Explanation:

The computation of the cost of direct labor in $ per customer is shown below:

= Total employee cost ÷ take order time

where,

Total employee cost equal to

= Each employee wages rate per hour × number of employees

= $7.5 × 5

= $37.5

And, the take order time is

= 30 × 4 employees

= 120

So, the cost of direct labor per customer is

= $37.5 ÷ 120

= 0.3125
