Final answer:
The dressmaker has a total of 720 inches of ribbon from the 10 rolls.
Step-by-step explanation:
We first need to convert the length of each roll from feet to inches. Since there are 12 inches in a foot, and each roll is 6 feet long, we multiply 6 by 12 to find the number of inches per roll:
6 feet/roll × 12 inches/foot = 72 inches/roll
Next, the dressmaker has 10 rolls of ribbon, so to find the total number of inches, we multiply the number of inches per roll by the number of rolls:
72 inches/roll × 10 rolls = 720 inches in total.
