Chapter 11– Work Backwards – Day 2

 

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 ˝ of money is sent to the stockbroker.

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?

POD – POD – Page 295, #11 Donuts

Four customers came into a bakery.  The first one said, “Give me half of all the donuts you have left, plus half a donut more.”  The second customer said, “Give me half of all the donuts you have left, plus half a donut more.”  The third customer said, “Give me three donuts.”  The last customer said, “Give me half of all the donuts you have left, plus half a donut more.”  This last transaction emptied the display case of doughnuts.  How many donuts were there to start with?

Hint:  If the bakery had 11 donut, then ˝ the donuts left plus ˝ a donut would be 5 ˝  + ˝ = 6, leaving 5 donuts.  The ˝ the donuts left and ˝ a donut works if the number of donuts left is odd.
