Afactory makes 1200 shirts every 6 hours. the factory makes shirts for 9 hours a workday. what is the fewest number of workdays the factory will need to make 12,600 shirts

1. Divide the target number of shirts, 12,600 by the company's rate of making the shirts. That is,
                                 number of hours = 12,600 shirts/ (1200 shirts/6 hours)
                                                               = 63 hours
2. Determine the number of workdays for them to complete the shirts by dividing 63 hours by 9 hours/workday. This will give us an answer of 7 workdays. 

X> -2 is the simplified version.
