With a group of 8 students you have set up a small business with which you help a customer every day during the holidays to clean up his computer and to redecorate it.
For the next day there are 12 possible customers. Everyone must got to one customer; so 4 customers can’t be helped that day.
For each combination, you know how much costs you have to incur to get a certain student to travel to a customer, this information is shown below in a table.
Of course you want to go to a layout where the total costs are minimal.
What is the minimum sum of the expenses if each student is going to help exactly one client, without students going to the same client?
