  4. 4. <ul><ul><ul><li>e) Create two different divisions of the liquid that Pete would think are fair. </li></ul></ul></ul><ul><ul><ul><li>Pete’s total pts = 456. Half of 456 = 228. So a fair division for Pete is a total of 228 pts. </li></ul></ul></ul><ul><ul><ul><li>2 possibilities are: (there are many others) </li></ul></ul></ul><ul><ul><ul><li>Division I : </li></ul></ul></ul><ul><ul><ul><li>Portion 1: 60 oz of milk and 48 oz of soda </li></ul></ul></ul><ul><ul><ul><li>3pts(60oz) = 180 pts for milk </li></ul></ul></ul><ul><ul><ul><li>1pt(48oz) = 48 pts for soda </li></ul></ul></ul><ul><ul><ul><li>Portion 2: 68 oz milk and 24 oz soda </li></ul></ul></ul><ul><ul><ul><li>Division II : </li></ul></ul></ul><ul><ul><ul><li>Portion 1: 70 oz milk and 18 oz soda </li></ul></ul></ul><ul><ul><ul><li>Portion 2: 58 oz milk and 54 oz soda </li></ul></ul></ul><ul><ul><ul><li>**Check pts and total ounces** </li></ul></ul></ul><ul><ul><ul><li>128 ounces of milk and 72 ounces of soda </li></ul></ul></ul>
  5. 5. <ul><ul><ul><li>f) Suppose Russell prefers soda to milk in a ratio of 5 pts to 4 pts . For each of the divisions from part (e), determine which portion Russell would choose and why? </li></ul></ul></ul><ul><ul><ul><li>Division I </li></ul></ul></ul><ul><ul><ul><li>5pts(60oz milk) = 300 AND 5(68) = 340 </li></ul></ul></ul><ul><ul><ul><li>4pts(48oz soda) = 192 4(24) = 96 </li></ul></ul></ul><ul><ul><ul><li> total=492 total = 436 </li></ul></ul></ul><ul><ul><ul><li>Russell chooses portion 1 = 492 pts </li></ul></ul></ul><ul><ul><ul><li>Division II </li></ul></ul></ul><ul><ul><ul><li>5 pts(70oz milk) = 350 AND 5(58) = 290 </li></ul></ul></ul><ul><ul><ul><li>4 pts (18oz soda) = 72 4(54) = 216 </li></ul></ul></ul><ul><ul><ul><li>total = 422 total = 506 </li></ul></ul></ul><ul><ul><ul><li>Russell chooses portion 2 = 506 </li></ul></ul></ul>
  6. 6. <ul><li>3. A team triathlon consists of a 16-mile run, an 80-mile bike ride, and a 9-mile swim. A team consists of three members. Matt’s running-to-biking-to-swimming ratio is 1 to 4 to 1. Jory’s ratios is 2 to 2 to 1 and Sart’s ratio is 3 to 1 to 4. The events will be divided according to the divide –and-choose method for three players. </li></ul>
  7. 7. <ul><ul><ul><li>a) How will each teammate value the entire race, and what would be a fair share according to each person? Complete the following table to help. </li></ul></ul></ul>54.67 164 4 1 3 Sart 67 201 1 2 2 Jorey 115 345 1 4 1 Matt Fair Share Total Pts 9-mile swim 80-mile bike 16-mile run
  8. 8. <ul><ul><ul><li>b) Would a 3-mile run, a 10-mile ride, and a 4-mile swim be considered a fair share by any of the three teammates? Justify your answer. (Hint: calculate how many pts this division would equal for each of the 3 players and then compare to your chart above.) </li></ul></ul></ul><ul><li>Matt’s pts: 3(1)+10(4)+4(1) = 47 </li></ul><ul><li>Jarey’s pts: 3(2)+10(2)+1(4) = 30 </li></ul><ul><li>Sart’s pts: 3(3)+10(1)+4(4) = 35 </li></ul><ul><li>Each is less than a fair share </li></ul>
  9. 9. <ul><ul><ul><li>4. Three kids, Holly, Harvey, and Hanna, must share a candy bar. For each of the following scenarios, describe the steps in a fair division of the candy bar using the last-diminisher method. </li></ul></ul></ul><ul><ul><ul><li>Holly makes the first cut. Harvey feels the portion is less than a fair share, so he does not make any cuts. Hanna also feels the portion is less than a fair share, so she does not make any cuts. How does this scenario proceed to an end? </li></ul></ul></ul><ul><ul><ul><li>Holly gets first piece (one she cut. The last person to cut gets his/her piece.) Harvey and Hanna use the divide and choose method. </li></ul></ul></ul>
  10. 10. <ul><ul><ul><li>b) Holly makes the first cut. Harvey feels the portion is less than a fair share, so he does not make any cuts. Hanna thinks the portion is too big, so she trims the piece. What happens next and how could this scenario end? </li></ul></ul></ul><ul><li>Hanna gets the portion she trimmed. The trimmings are combined with the rest of the candy bar. Holly and Harvey divide and choose. </li></ul>
  11. 11. <ul><ul><ul><li>5. Twins Else and Emma receive a painting from their grandmother. Both girls admired the painting often, and the grandmother could not decide which one to give it to. Else believes the painting is worth $780 and Emma feels it is worth $835. The girls both want the painting, but they agree to use the method of sealed bids to help them create a fair division. What is the result of the division? Show all work. </li></ul></ul></ul>
