Final answer:
To calculate the price per inch of a plant, divide the total cost by the plant's height. For a plant costing $2.28 at 9.5 inches tall, the price per inch is $0.24.
Step-by-step explanation:
To find the price per inch of a plant, we need to divide the total price of the plant by its height in inches. In this case, Bob has a plant that is 9.5 inches high and costs $2.28. Therefore, we perform the following calculation:
Price per inch = Total price / Height in inches
Price per inch = $2.28 / 9.5 inches
Price per inch = $0.24 per inch
So, the price per inch of a plant in Bob's store is $0.24.
