Nena (an 80's pop band from Germany) sang a song about 99 balloons (they were "luftballoons" in German, but in English, they were "red balloons").

If the sound level of a single balloon popping is 142 dB, what is the minimum number of the 99 balloons that would need to simultaneously pop in order to create a noise with a sound level that is 12 dB louder? (Such that the sound level of the balloons popping simultaneously would be 154 dB?)

Balloons

Hint: If your answer was 5.432, can you actually pop 5.432 balloons? Remember that you need the sound level to be at least 154 dB
