During each six-hour period of the day, the Bloomington Police Department needs at least the number of police officers shown in the file P04_125.xlsx. Po-lice officers can be hired to work either 12 consecutive hours or 18 consecutive hours. Police officers are paid $15 per hour for each of the first 12 hours they work in a day and $23 per hour for each of the next six hours they work in a day. Determine how to minimize the cost of meeting Bloomington’s daily police requirements.
