Two types of computer consultants can be hired: full$-$time and part$-$time. The full$-$time consultants work for eight consecutive hours in

any of the following shifts: morning $(8$ AM to $4$ PM $),$ afternoon $($noon to $8$ PM $),$ and evening $(4$ PM to midnight$).$ Full$-$time consultants are

paid $$17\mathrm{.}50$ per hour. Part$-$time consultants can be hired to work any of the four shifts listed in the table. Part$-$time consultants are paid

$$15$ per hour. An additional requirement is that during every time period, there must be at least two full$-$time consultants on duty for

every part$-$time consultant on duty.

Formulate a spreadsheet model for this problem. Then use Solver to solve the model.

a$.$ Larry would like to determine how many full$-$time and part$-$time consultants should work each shift to meet the above requirements

at the minimum possible cost.

Note: Enter $"0"$ if no workers are assigned during that particular shift.

b$.$ Determine the total cost.
