An anthropologist compares two prehistoric tool sites. Site A has 120 tools with an average weight of 1.8 kg, Site B has 180 tools averaging 2.4 kg. If she combines the collections, what is the overall average weight per tool?

**An anthropologist compares two prehistoric tool sites. Site A has 120 tools with an average weight of 1.8 kg, Site B has 180 tools averaging 2.4 kg. If she combines the collections, what is the overall average weight per tool?** Across the American heartland and beyond, prehistoric tool sites are drawing fresh attention from researchers and curious minds alike. What makes a simple collection of stone tools meaningful to modern audiences? One compelling insight stems from recent comparative studies analyzing two such sites—Site A and Site B—each revealing distinct patterns in material culture. Together, they offer a compelling snapshot of early human innovation and trade dynamics in prehistoric North America. Understanding average artifact weight helps researchers interpret tool use, mobility, and cultural exchange. In this analysis, Site A accounts for 120 tools averaging 1.8 kilograms, while Site B contributes 180 tools averaging 2.4 kilograms. Rather than treating these numbers in isolation, combining them provides a broader lens on tool economy across regions. **What does the math actually reveal?**
