The Ferris college of business is replacing older copy machines with state of the art ones. Currently, there are 12 old copy machines. the room housing the copy machines is only open one 8 hour shift each day, 5 days per week (Monday thru Friday). Using the new copy machines, each professor's copy order takes 5 minutes while staff copy orders take 3 mins each. Weekly need from professors is 900 copy orders while staff needs to process 2000 copy orders.

1.)What is the correct formula for this problem

2.)Calculate the processing time available (for the week) for machines use - in minutes

3.)Calculate the following in minutes: the processing time needed (to meet the week's demand) for professor orders is _____ and the processing time needed (to meet the week's demand) for staff orders is ____________

4.)Calculate the number of required machines in minutes:

-The numerator in the required formula

-The denominator in the required formula

-The calculated number of required machines (without rounding) is

-With rounding the correct number of required machines is
