Answer :
To complete the order of 660 units in 9 days, the manufacturer would need 10 machines. To determine the number of machines needed to complete the order in 9 days, we need to calculate the total machine time required and divide it by the available machine time per day.
Given data:
Number of units: 660
Machine time per unit: 100 minutes
Available machine time per day: 13 hours = 13 * 60 minutes = 780 minutes
Number of days: 9
Total machine time required = Number of units * Machine time per unit
= 660 * 100
= 66,000 minutes
Number of machines needed = Total machine time required / (Available machine time per day * Number of days)
= 66,000 / (780 * 9)
≈ 9.4
Since we can't have a fraction of a machine, we need to round up the number of machines to the nearest whole number:
Number of machines needed = 10
Therefore, to complete the order of 660 units in 9 days, the manufacturer would need 10 machines.
