To find out how much paper remained on the roll after Taylor made her sign, you can subtract the amount of paper she used from the total amount of paper on the roll.
Total paper = 123 yards
Paper used = 56 yards
Remaining paper = Total paper - Paper used
Remaining paper = 123 yards - 56 yards = 67 yards
It seems there was a mistake in the question as 67 yards is not one of the answer choices provided. Please recheck the information given.
