It is decided that the three of them will divide the 8 sandwiches equally, and then Al and Bert will divide the $8. After lunch, Bert picks up four of the dollars. but Al says that it is not fair. He says he should have more. Carl agrees that All should have nore. He says that since Al contributed 5 of the sandwiches and Bert contributed 3, Al should get $5 and Bert should get $3
Is this the most fair division of the money?
