The store estimates that its profit per racquet will vary with the manufacturer as shown below:
racquet manufacturer | R1 | R2 | R3 | R4 | R5 |
| M1 | 5.5 | 7 | 8.5 | 4.5 | 3 |
| M2 | 6 | 6.5 | 9 | 3.5 | 2 |
| M3 | 5 | 7 | 9.5 | 4 | 2.5 |

We have 3 workgroups, which can work 8 hours each. They have to manage 7 orders which take 2,2,11,2,1,3, and 2 hours to be finished. Moreover, every workgroup has its own abilities, which means that the first workgroup can work on order 3,4,5 and 6, the second on 1,2,3,5,6 and 7, and the third on 1,2,3 and 5.
