Two beachcombers were about to sit down to a meal of coconuts. One had brought two coconuts, and the other had brought three. As they were about to begin, a mermaid arrived, and they invited her to join them. When they had finished the contents of the five coconuts, each eating an equal share, the mermaid thanked the others. She tossed five sand dollars down on the beach, asking the others to accept them as payment for her share of the meal and to divide them fairly, according to what each had contributed. How should the two beachcombers divide the sand dollars?
