Tom and Gina are going hiking in the desert, and Tom is responsible for carrying as much water as he can with him. Unfortunately, however, he has only a few fixed sizes of water bottles into which he can put the water, and he can only carry 15.00 kg at most.
If his bottles have the following masses, and he can carry as many of each as he likes (so long as the total is less than or equal to 15 kg), what is the most amount of water that Tom can carry?
