6/10 correctWhat is the hardest natural substance on Earth?
The hardest natural substance on Earth is **diamond**.
Diamond’s crystal structure—a tetrahedral lattice of carbon atoms—gives it an unparalleled resistance to scratching and indentation, ranking it at 10 on the Mohs hardness scale. No other naturally occurring material matches this combination of rigidity, strength, and thermal conductivity.

Janet's ducks lay 16 eggs per day. She eats 3 for breakfast every morning and bakes muffins for her friends every day with 4 eggs. She sells the remainder at the farmers' market daily for $2 per fresh duck egg. How much in dollars does she make every day at the farmers' market?
Janet has a supply of \(16\) eggs each day.
She uses:
- \(3\) eggs for her breakfast
- \(4\) eggs to bake muffins for friends
That is a total of \(3 + 4 = 7\) eggs used.
The remainder available for sale is
\[
16 - 7 = 9 \text{ eggs}.
\]
At the farmer's market she sells each fresh duck egg for \(\$2\).
So her daily earnings from the market are
\[
9 \text{ eggs} \times \$2 \text{ per egg} = \$18.
\]
\[
\boxed{\$18}
\]

Sam bought a dozen boxes, each with 30 highlighter pens inside, for $10 each box. He rearranged them into packs of 6 pens each and sold them for $5 per pack. How much profit did he make in total?
First, calculate the total cost:
- He bought 12 boxes.
- Each box cost $10.
\[
\text{Total cost} = 12 \times \$10 = \$120
\]
Now, find out how many 6‑pen packs he could make:
- Each box has 30 pens, so 12 boxes have \(12 \times 30 = 360\) pens.
- A pack contains 6 pens.
\[
\text{Number of packs} = \frac{360}{6} = 60
\]
Next, compute the revenue from selling those packs:
- Each pack sold for $5.
\[
\text{Total revenue} = 60 \times \$5 = \$300
\]
Finally, subtract the cost from the revenue to get the profit:
\[
\text{Profit} = \text{Revenue} - \text{Cost} = 300 - 120 = \$180
\]
**Sam’s total profit is \$180.**
