When we visited the coal mines that dot the landscape of West Virginia, our tour guides were happy to give us pieces of coal as souvenirs to take home! But not everybody was treated fairly. My friend Olivia got 2 pieces of coal, but my other friend Melissa only received 1. Anjali got 2 pieces, Francois and Martin each got 1 piece, and Maximilian and Sijia each got 3 pieces. How many pieces did my friends Alessandro, Yuanyuan, and Penelope receive in total? _
