The hardest natural substance onEarth is **diamond**. It is composed of carbon atoms arranged in a crystalline structure, giving it an extremely rigid lattice. On the Mohs scale of mineral hardness, diamond scores a perfect **10**, meaning it can scratch any other natural material. ### Key Points: - **Mohs Scale**: Diamond is at the top of this scale (10), with 10 being the highest hardness. - **Natural Formation**: Diamonds form deep within the Earth's mantle under high pressure and temperature, and brought to the surface via volcanic eruptions. - **Lonsdaleite**: A rare, hexagonal form of diamond found in meteorite impact sites, sometimes theorized to be slightly harder under specific conditions, but diamond remains the definitive answer for most practical and widely accepted contexts. No other natural substance—whether mineral, gem, or organic material—matches diamond's hardness under normal Earth conditions.

To determine Josh's profit,we first calculate the total cost he invested: $80,000 (purchase) + $50,000 (repairs) = **$130,000**. The repairs increased the house's value by **150%** of its original price. A 150% increase means the new value is: Original value + 150% of original = $80,000 + (1.5 × $80,000) = **$200,000**. Profit is then the new value minus total costs: $200,000 - $130,000 = **$70,000**. **Answer:** Josh made a profit of **$70,000**.

Sam's total costfor the boxes is 12 boxes * $10/box = $120. He has 12 * 30 pens = 360 pens in total. Divided into packs of 6, he makes 360 / 6 = 60 packs. Selling each pack for $5, his revenue is 60 * $5 = $300. Profit is revenue minus cost: $300 - $120 = **$180**. **Answer:** $180
