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 14 deluxe wreaths, which used a total of 160 pinecones. After lunch, they assembled 15 regular wreaths and 15 deluxe wreaths, using a total of 180 pinecones. How many pinecones are they putting on each wreath?

Answer 1

Before lunch, they assembled a total of 12 + 14 = <<12+14=26>>26 wreaths.
After lunch, they assembled a total of 15 + 15 = <<15+15=30>>30 wreaths.
They used a total of 160 + 180 = <<160+180=340>>340 pinecones.
Therefore, they used 340/56 = <<340/56=6.071428571428571>>6.071428571428571 pinecones per wreath.
Therefore, they put an average of 6 pinecones on each wreath. Answer: \boxed{6}.
