Can you put up one of those balance scale problems with some kind of New Years' theme to it?
Dear Michael M.,
Here it is. . .
NEW YEAR'S EVE BALANCE
A series of weighings is shown here. The items on the scales are party hats, noisemakers, and plastic cakes to decorate a room where a party is going to be held.
The first two scales (scale A and scale B) are balanced and complete. But the third scale (scale C) is not.
QUESTION: Based on what you see below, how many of the plastic cakes would you need to place on the right-hand side of scale C in order to form a balance with the 3 hats and the 3 noisemakers on the left-hand side of that scale?
