Explain why the answer to this question is 6, and not 15:

• The answer actually is 15, NOT 6.

• Neither answer is correct for this problem.

• Because 6 is the number of days, and the question is asking for the number of ribbons left.

• Because 15 is the number of ribbons left, and the question is asking for the number of days.
