Hardwood flooring that costs $16 for every 2 square feet. A concrete patio quoted at a bulk cost for 50 square feet. Sod that is quoted at a set price per square yard plus a labor fee. Pavers that cost a set amount per square foot.
Cost Is Proportional to Area
Cost Is NOT Proportional to Area
Not Enough Information
The answer is: Cost Is Proportional to Area.
Explanation: The hardwood flooring, concrete patio, and pavers all have costs quoted based on area (square feet or square yards). This means their costs increase as the area increases, indicating a proportional relationship. However, since sod includes a labor fee, which is a fixed cost regardless of area, its total cost may not be purely proportional to area. Thus, the correct answer is based on the provided information regarding each material’s pricing structure.
