Given the following reasoning and answer, what was the question? The band played 5 + 7 = 12 songs in their first two sets. They have 30 - 12 = 18 songs left for the third set, fourth set and encore. Since they played 2 songs in the encore, they have 18 - 2 = 16 songs to play on the third and fourth sets. They will play 16 / 2 = 8 songs on average over the third and fourth sets.
The answer: 8
The question The school band has 30 songs in their repertoire. The band played 5 songs in their first set and 7 in their second set. The band will play 2 songs for their encore. Assuming the band plays through their entire repertoire, how many songs will they play on average in the third and fourth sets?
