Final answer:
To determine the price per inch of rope, convert 3 yards to inches (108 inches) and then divide the total cost ($162) by the number of inches.
Step-by-step explanation:
The student has asked us to calculate the price per inch for a 3-yard piece of rope that costs $162. To find the price per inch, the first step is to convert yards to inches. There are 36 inches in a yard, so 3 yards is equal to 108 inches (3 yards times 36 inches). Next, to find the price per inch, we divide the total cost by the number of inches. Therefore, $162 divided by 108 inches gives us the price per inch.
