Thanks for your time, Tina Date: 8/30/96 at 16:15:43 From: Doctor Alain Subject: Re: Ways to Make 50c To solve this kind of problem, it is important to sort the different ways you find properly. I live in Canada, where we have a 50 cent coin. I'm not sure if you have one, but this is the way I would do it. Part 1 How many ways can I make 50c using a single 50c coin (that's easy). Part 2 How many ways can I make 50c using no 50c coin (that's harder). Part 2.1 How many ways can I make 50c using no 50c coin and 2 quarters. Part 2.2 How many ways can I make 50c using no 50c coin and 1 quarter. Part 2.2.1 How many ways can I make 50c using no 50c coin and 1 quarter and 2 dimes. Part 2.2.2 How many ways can I make 50c using no 50c coin and 1 quarter and a single dime. ...etc... Part 2.2.3 How many ways can I make 50c using no 50c coin and no quarter and no dime. ...etc... Part 2.3 How many ways can I make 50c using no 50c coin and no quarters. ...etc... Then you just add the answers found in the different parts. I also get 50 ways. -Doctor Alain, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
