Ten jobs are to be completed by three workers (Sam, Joy, and Kelly) during the next

week. Each person works a 40-hour week and is paid an hourly rate: Sam, Joy, and Kelly

earn $11, $13, and $14 per hour, respectively. Union rules require workers to be treated

fairly; to ensure that most of the work is not assigned to one person while others are too

idle, make sure that no person works more than 8 hours above any other worker. For

example, if Joy works 20 hours, then Sam and Kelly should work within 12 to 28 hours,

and Sam and Kelly should have work-hours that are no more than 8 hours apart.

The times for the workers to complete the tasks are shown in the table below. The values

in the cells assume that each task is completed by a single person. However, tasks can be

shared with completion times being determined proportionally (e.g. if Joy and Kelly

share task 1 equally, then Joy works 6 hours and Kelly works 9 hours). If no entry exists

in a particular cell, it means that task cannot be performed by that worker.

As above.<br><br>

We're most likely getting married outside, and around late morning. Even though it's a wedding...to me, a big white gown doesn't fit with the surroundings/situation. <br><br>

There are another reason why I don't really want a big white gown either. I don't wear dresses very often but when I do I always buy quality. Wedding dresses seem to be too expensive for the quality they a
