yellow. How many more blue balloons were sold than yellow?

55 balloons were yellow.

73 balloons were blue

89 balloons were orange

Answer 1

To answer the question, "How many more blue balloons were sold than yellow?", we only need the number of blue balloons sold and the number of yellow balloons sold.

The relevant information is:

• 73 balloons were blue.
• 55 balloons were yellow.

The information that is NOT necessary to answer the problem is:

• 89 balloons were orange (since the count of orange balloons does not affect the difference between blue and yellow).

Thus, the unnecessary information is "89 balloons were orange."
