0.1472 hours or 8.832 minutes

Explanation:

Annual demand - 23,000 units

Daily demand - 92 units

Daily production - 960 units per 8 hour day

Desired lot size - 120 units

Holding cost per unit per year - $13 per unit

Set up labor cost per hour - $25 per hour

Set up cost:

= { (120 * 120) * $13 * [1 - (92 : 960) ]} : [2 * (23,000) ]

= $169,260 : 46,000

= $3.68

Set up time:

= Set up cost : Set up labor cost per hour

= $3.68 : $25 per hour

= 0.1472 hours or 8.832 minutes
