What is the relationship between the number of green and red balloons used by Cassandra if she used 5 more green balloons than red balloons?

Back

If Cassandra used 5 more green balloons than red balloons, and she used 11 red balloons, then the number of green balloons is calculated as: 11 (red) + 5 = 16 (green).
