An I.T. team repairs computers that break down at an average of = 2.5 per hour (approximately Poisson in nature). The team can service an average of 2 computers every 30 minutes with a repair time distribution that approximates an exponential distribution. The department is open 10 hours per day. The teams approximate cost $125 per hour. The cost associated with lost productivity from the breakdown is estimated at $55 per hour (or any fraction thereof).

A) What is the utilization rate? Options: [85.3%, 38%, 47%, 79.5%, 62.5%]

B) What is the number of computers waiting to be serviced? Options: [1.67, 1.04, 2.89, 1.23, 0.66]

C) How long before a breakdown is serviced (minutes)? Options: [0.67 of an hour, 25 minutes, 35 minutes, 0.75 of an hour, 40 mintutes]

D) Based on total system cost (Ls), what is the expected daily cost? Options: [$216.67, $2,166.67, $182.29, $2,045.50, $1,822.92]
