Question

Under ideal​ conditions, a service bay at a Fast Lube can serve 8 cars per hour. The effective capacity of a Fast Lube service bay is 6.0 cars per​ hour, with efficiency known to be 0.85. The minimum number of service bays Fast Lube needs to achieve an anticipated production of 200 cars per 8​-hour day​ = nothing service bays ​(enter your response rounded up to the next whole​ number).

Answer 1

Actual Output = 200 cars

Effective capacity= 6 per hour = 6 x 8 = 48/ day for on Bay

Efficiency = 0.85

n= total number of bays needed

Effiency = Actual output / Effective Capacity

0.85 = 200/ (48 X n )

n = 4.90 = 5
