t takes an operator 0.80 minute to service a machine and 0.1 minute to walk to the next machine. Each machine runs automatically for 6 minutes, the operator earns $15.00/hour and the machines cost $25.00/hour to run. After calculating n1 and n2, How much is the production rate per hour R, with n1 and n2?

A. Rn1 = 36.4 Rn2 = 42.9

B. Rn1 = 34 Rn2 = 35.3

C. Rn1 = 61.8 Rn2 = 66.7

D. Rn1 = 38.7 Rn2 = 40

E. Rn1 = 45 Rn2 = 50
