The raisin bread
Three friends, Bill, Jack, and Tim were hiking in a park exploring the
wilderness when Bill felt hungry. He suggested that they take a break
under the shade of a large oak tree.
"Let's eat. I brought seven raisin bread here," Bill said as he took out a
brown paper bag from his backpack.
"Hey, I have five pieces of the same bread. We must have bought them
from the same baker," Jack exclaimed upon seeing Bill's bread.
"Sorry guys, I did not bring any food," Tim said with dismay.
"It's alright, we can have four pieces each," Jack answered.
"OK, but I'll pay for my share in fairness to both of you," Tim insisted.
So Bill, Jack, and Tim each ate four pieces of raisin bread. After
finishing their meal, Tim took $12 out of his leather wallet.
"Here is $12, share it equitably with Jack," Tim said as he gave the money
to Bill.
"How should we split it?" Bill asked.
"Keep $7 for your seven bread, and just give me $5 for my five bread. That
makes each bread $1 even," Jack said to Bill.
How should the $12 be shared between Bill and Jack?
