A shipping company operates a docking facility for cargoes. We obtain the following table. The time unit is hour. Suppose that the cost of each team is $100 per hour and cost of waiting per cargo per hour is $200. If you use 5 servers (5 teams of workers), how much is the total operational cost of the system per hour? (Consider both labor cost and waiting cost.)

A

$450

B

$526

C

$504

D

$508

E

$660

F
