Final answer:
To find out how many feet of fabric are left on the roll, we need to convert the yards and feet into the same unit. First, we convert 3 yards into feet, which gives us 9 feet. Next, we convert 4 feet into yards, which gives us 1.33 yards. Finally, we subtract the amount of fabric Lou cut from the original length of 9 yards and convert it back into feet, resulting in 13 feet.
Step-by-step explanation:
To find out how many feet of fabric are left on the roll, we need to convert the yards and feet into the same unit.
First, we know that 1 yard is equal to 3 feet, so 3 yards is equal to 3 x 3 = 9 feet.
Next, we can convert the 4 feet into yards by dividing it by 3. So, 4 feet is equal to 4 / 3 = 1.33 yards.
Finally, we subtract the amount of fabric Lou cut from the original length of 9 yards, which is 3 yards + 1.33 yards = 4.33 yards.
Converting this back into feet, we have 4.33 yards x 3 = 13 feet.
