C&A Fast Food has four activities in serving a customer: greet customer, take order, process order, and deliver order. Each activity is staffed by one employee (for a total of four employees). The processing time for each activity is given as follows:

Activity	Processing time per customer
Greet customer	2 seconds
Take order	30 seconds
Process order	60 seconds
Deliver order	5 seconds

Assume demand is unlimited. Each employee is paid $7.50 per hour. If one additional employee is added to the bottleneck activity, what will be the cost of direct labor in $ per customer?
