A bank needs exactly two employees working each hour from 9 A. M. to 5 P. M. Workers can work the shifts and are paid the wages listed in the file P04_74.xlsx. For example, a worker working 9 A. M. to 2 P. M. is paid $42.00. Find an assignment of workers that provides enough workers at minimum cost. (Is it even possible to have exactly two employees working each hour? If not, make sure at least two are working each hour).
