The glee club needs to raise money for the spring trip to Europe, so the members are assembling
holiday wreaths to sell. Before lunch, they assembled
12 regular wreaths and 20 deluxe wreaths, which used a total of 168 pinecones. After lunch, they assembled
12 regular wreaths and 15 deluxe wreaths, using a total of 138 pinecones.
How many pinecones are they putting on each wreath?
~~~~~~~~~~~~~~~~~~~
To be in style, solve it MENTALLY, smiling.
After reading the condition, a student should notice that the difference between
the morning production and the afternoon production is 20-15 = 5 deluxe wreaths
and 168-138 = 30 pinecones.
Hence, each deluxe wreath has 30/5 = 6 pinecones.
Then each regular wreath has  = 4 pinecones.
Solved.
