The question is: At a birthday party, there are 20 red balloons and 15 green balloons. Before the party started, 3 red and 2 green balloons burst. How many balloons are left?
Step-by-step reasoning process: There are a total of 20 + 15 = 35 balloons at the party. Out of the 35, 3 + 2 = 5 balloons burst. Thus, only 35 - 5 = 30 balloons are left.
