Answer:
$0.5 per customer
Explanation:
The computation of the cost of the direct labor is shown below:
Since the processing time is given, so we take the minimum time out of available ones
Greet customer = 1 ÷ 2 seconds
Take order = 1 ÷ 30 seconds
Process order = 1 ÷ 60 seconds
Deliver order = 1 ÷ 5 seconds
Minimum is 1 ÷ 60 seconds
Now total customer per hour is
= 1 ÷ 60 seconds × 60 × 60
= 60 customer pee hour
And, for total employee, the paid cost is
= $7.50 × 4
= $30 per hour
So, the cost of direct labor is
= $30 per hour ÷ $60 per hour
= $0.5 per customer
