Compute the operating characteristics if the company retains the single-employee repair operation. If required, round your answers to four decimal places.

P₀ = fill in the blank 1

L_q = fill in the blank 2

L = fill in the blank 3

W_q = fill in the blank 4 hours

W = fill in the blank 5 hours
Compute the operating characteristics if a second employee is added to the machine repair operation. If required, round your answers to four decimal places.

P₀ = fill in the blank 6

L_q = fill in the blank 7

L = fill in the blank 8

W_q = fill in the blank 9 hours

W = fill in the blank 10 hours
Each employee is paid $30 per hour. Machine downtime is valued at $85 per hour. From an economic point of view, should one or two employees handle the machine repair operation? Explain. If required, round your answers to two decimal places.

Cost of one employee system: $ fill in the blank 11
