Final answer:
To find the price per inch of a 7-foot ribbon that costs $9.24, convert feet to inches, resulting in 84 inches, and then divide the total cost by the number of inches, which gives you $0.11 per inch.
Step-by-step explanation:
To calculate the price per inch for a 7-foot ribbon that costs $9.24, you first need to convert feet to inches. There are 12 inches in a foot, so you multiply 7 (feet) by 12 to find out how many inches are in the ribbon. Then, divide the total cost of the ribbon by the number of inches to get the price per inch.
- Convert feet to inches: 7 feet × 12 inches/foot = 84 inches.
- Calculate the price per inch: $9.24 / 84 inches = $0.11 per inch.
Therefore, the cost of the ribbon is $0.11 per inch.
