The answer is $8.33 per cubic yard.
Explanation:
This problem is just a normal math equation. You divide the price by how much space you are covering to get the smallest ratio(15 million divided by 1.8 million). After dividing you get the answer of $8.33 per cubic yard.
Carbon atoms have 4 valence electrons. That allows them to make 4 covalent bonds. That means they can make really big molecules. All the organic molecules have Carbon in them.
