I think that the 2 or 4 one are right. This one is hard for me too but just hope that you get right and hope that it is right.
Graph #4. Shaded portions of the graph represent the possible solutions. The maximum amount of birdies the coach can buy is 25 (4x25=100), which is why the red does not go further than 25. The maximum amount of rackets the coach can buy is 10 (10x10=100). The purple area represents numbers of BOTH rackets and birdies the coach can buy.
