Chapter 11– Work Backwards – Day 1

 

POD - POD –Classic Mustangs

          None of us really got along as friends, but we shared several things in common.  We had some joint business dealings and a love of old Mustangs.  We only liked the ones from 1964 ½ through the 1968 model year.  When we found out that the collection of Mustangs from the Sparks Auto Museum was going to be auctioned off, we put our minds and our money together.  Instead of bidding against each other, we decided to bid as a group on each Mustang available.  We set a maximum price we would bid, and quite frankly, none of us had any favorites, we loved them all equally.  We also agreed to divide “out take” as follows:  half to Travis because he was usually the big money on our projects, ¼ to Sandra as she was usually the brains that got things done, and I was to get a 1/6 share.  In the end we were the winning bidders on 11 Mustangs.  How many Mustangs does each of us get?

Finishing Chapter 9

IN CLASS - #8 – page 245 – Twenty-Five-Man Roster

          The manager of a baseball team received a strange communication from the team’s general manager, who told him to select 25 players for his roster according to this formula:

          ½ of the team had to be outfielders and infielders

          ¼ of the team had to be starting pitchers

          1/6 of the team had to be relief pitchers

          1/8 of the team had to be catchers.

          The manager was taken aback by the innumeracy exhibited by his boss, yet he found a way to comply.  How did he do it?

 

IN CLASS – Slick Sam

Sam goes to store with some money.  If you give me $50, I’ll spend 1/2 of all my money.  He does the same in a 2nd store and again in a 3rd store and a 4th store.  When he leaves the 4th store he has $75.  How much money did he start with?

IN CLASS – Game Players

Three girls play three rounds of a game.  On each round there are two winners and one loser.  The girl who loses on a round has to double the number of chips that each of the other girls has by giving up some of her own chips.  Each girl loses one round.  At the end of three rounds, each girl has 40 chips.  How many chips did each girl have at the beginning of the game?

Ramon took a collection of colored tiles from a box.  Amelia took 13 tiles from his collection, and Keiko took half of those remaining.  Ramon had 11 left.  How many did he start with?

 

IN CLASS - Sharing Blocks

A box of blocks was sitting on a table in a classroom.  Mindy decided to play with the blocks and took one third of them to her desk.  John thought this was a great idea and took one third of the blocks that remained in the box.  A moment later Jim took one third of what then remained, leaving 16 blocks in the box.

b. How many did each of the children have to play with?

 

IN CLASS - Page 295, #10 - Two for Tennis

Scott and Jeremy took a basket of balls with them to tennis practice.  Scott took out two and three them at Jeremy.  Jeremy chased Scott and accidentally knocked over the basket, dumping out five-eights of the remaining balls.  Scott threw three back in.  As they were playing, a hard hit knocked the basket over, and one-fifth of the remaining balls rolled out.  Scott put two balls back into the basket, but a couple of minutes later a smash hit knocked the basket over again.  Half the remaining balls rolled out, and then there were seven left in the basket.  How many tennis balls did Scott and Jeremy start with in the basket?

 

POD – Invest That Money!

A businesswoman went to the bank and sent half of her money to a stockbroker.  Other than a $2 parking fee before she entered the bank and a $1 mail fee after she left the bank, this was all the money she spent.  On the second day she returned to the bank and sent half of her remaining money to the stockbroker.  Once again, the only other expenses were the $2 parking fee and the $1 mail fee.  If she had $182 left, how much money did she have before the trip to the bank on the first day?  Note:  She pays the parking before she goes into the bank, and the mail fee is after the ½ of money is sent to the stockbroker.
