Larry Edison is the Director of the Computer Center for Buckly College.  He now needs to schedule the staffing of the center.  It is open from 8 AM until midnight.  Larry has monitored the usage of the center at various times of the day and determined that the following numbers of computer consultants are required:

Two types of computer consultants can be hired: full-time and part-time. The full-time consultants work for eight consecutive hours in either one of the following two shifts: morning (8 AM - 4 PM), and evening (4 PM - Midnight). Full-time consultants are paid $14.00 per hour.

Part-time consultants can be hired to work any of the four shifts listed in the table.  Part-time consultants are paid $12.00 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. 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.
