[Question]: Brenda picks 250 peaches. When she sorts through them, only 60% are fresh, and Brenda has to throw 15 away for being too small. How many peaches does Brenda have left?
[Answer]: First find how many of the peaches are fresh, which is 250 peaches * 60% = 150 peaches. Then, subtract the number Brenda throws away after the fresh count, which is 150 peaches - 15 peaches = 135 peaches.
So the answer is 135.

[Question]: May can knit 3 scarves using one yarn. She bought 2 red yarns, 6 blue yarns, and 4 yellow yarns. How many scarves will she be able to make in total?
[Answer]: May will be able to make 2 x 3 = 6 red scarves. She will be able to make 3 x 6 = 18 blue scarves. And she will be able to make 4 x 3 = 12 yellow scarves. Therefore the total scarves she can make is 12 + 18 + 6 = 36.
So the answer is 36.

[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?
[Answer]:
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.
So the answer is 8.
