School is in
full swing for me and for my nephews, Barney and Danny, and their little
cousin, Gina. In fact, last Friday evening their school had a "Fall
Festival" and we all went together.
One game we wanted to play was at the “Balance Booth”.
At the booth there were 5 bags of delicious candy. If you can put
them on a pan balance so that they balance perfectly, you win all 5 bags of
candy! The bag of Jelly Wigglers weighed 8 ounces, the Party Pops weighed 3
ounces, the Sour Powder weighed 2 ounces, the Candy Dots weighed 3 ounces, and
the Mello Mints weighed 4 ounces.
Now, here are the rules. The candy has to stay in the bags. You
cannot open the bags. You have to use all the bags of candy and once you put a
bag of candy on the balance, you cannot move it. If the pans are balanced
perfectly at the end, you win them all. However, if one side tips lower than
the other, you lose!"
What combinations could be used to perfectly balance your pan
Assign each bag a variable
and write an equation with one unknown for your solutions.
