Answer:

d. Decrease by 0.045 minutes

Explanation:

First Case  

Time per unit for 250 batch size = (30 / 250) + 5 minutes

Time per unit for 250 batch size = 5.12 minutes

Second case

Time per unit for 250 batch size = (30 / 400) + 5 minutes

Time per unit for 250 batch size = 5.075 minutes

The decrease in manufacturing time = Old-time - New time  = 5.12 - 5.075  =  0.045 minutes . So, it Decrease by 0.045 minutes
