Final answer:
Calculating the cost of hardwood flooring for a 4x17 feet hallway at $5.48 per square foot results in a cost of $372.64. No additional information suggests a higher potential cost, providing us with a single value rather than a range.
Step-by-step explanation:
The question involves calculating the cost of hardwood flooring based on a given area and unit price. To find the range of the actual cost, we need to multiply the area of the hallway by the price per square foot. First, we calculate the area of the hallway (4 feet by 17 feet) which equals 68 square feet. Then, we multiply the area by the unit price of $5.48 per square foot.
The cost to cover the hallway with hardwood flooring would be 68 square feet × $5.48 per square foot = $372.64. Since the question asks for a range and does not provide additional costs such as labor or materials, we can assume the lowest end of the range would be just the cost of materials, which we have calculated. However, without additional costs or further context, we can't determine a higher end of the range, restricting us to a single value.
