Answer Key for 11/23/15 and request for help

Smith MathCounts Club,

Looking for more practice?  Don't forget AOPS MathCounts Trainer program:

The School MathCounts Competition is only two weeks away (Monday, Dec. 14).  Medals and trophies have been ordered.  There is a first place trophy and 2nd and 3rd place medals for each grade level.  I expect we will end up with close to 70 students competing.  About the top 15, including some from each grade level, will continue training as part of the Smith MathCounts Team.  The MathCounts Club will be over for this year for the rest of us.

We will have refreshments and a small party after the contest (while the tests are being scored in a back room) followed by a short awards ceremony.  I need some parent help with:

- bring in refreshments (drinks, salty and sweet snacks)

- supervising students in library from 4:00 - 5:00

- scoring tests

Please email me if you can help with any of this.  Thanks!
