Answer :
The number of vats to be used is 8
Given: Weight of material used per day = 196 pounds
Weight of each vat = 26 pounds
Cycle time for each vat = 2.5 hours
Inefficiency factor assigned by manager = 25%
Time available for each day = 8 hours
To calculate the number of vats to be used, we need to calculate the time required to transport the total material by the available vats.
So, the number of vats required = Total material weight / Weight of each vat
To calculate the total material weight transported in 8 hours, we need to calculate the time required to transport the weight of one vat.
Total time to transport one vat = Cycle time for each vat / Inefficiency factor
Time to transport one vat = 2.5 / 1.25
(25% inefficiency = 1 - 0.25 = 0.75 efficiency factor)
Time to transport one vat = 2 hours
Total number of vats required = Total material weight / Weight of each vat
Total number of vats required = 196 / 26 = 7.54 (approximately)
Therefore, the number of vats to be used is 8 (rounded up to the next whole number).
Answer: 8 vats will be used.
