We have a question: Liz's basketball team is down by 20 points in the final quarter of their game. Liz goes on a shooting spree, sinking 5 free throw shots, 3 three-pointers, and 4 other jump shots. The other team only scores 10 points that quarter, and none of Liz's teammates manage to score any points. How much does Liz's team lose by at the end of the game?
And an answer: 8
So how you got the answer?
Each free throw counts as 1 point, so 5 successful free throws means she scores 5 * 1 = 5 points. Each 3 pointer counts as 3 points, so this means Liz scores 3 * 3 = 9 points from 3 pointers. Each jump shot counts as 2 points, meaning Liz scores 4 * 2 = 8 points of jump shots. Liz's opponents score 10 points during the quarter, meaning their lead is 30 points in total before accounting for Liz's scoring. Liz scores a total of 5 + 9 + 8 = 22 points in the quarter. This amount is subtracted from the lead of Liz's opponents, meaning they win by 30 - 22 = 8 points.

We have a question: Carl buys index cards for his class. He gives each student 10 index cards. He teaches 6 periods a day and each class has 30 students. If a 50 pack of index cards cost $3 how much did he spend on them all?
And an answer: 108
So how you got the answer?
He has 30 * 6 = 180 students. So he needs to buy 180 * 10 = 1800 index cards. That means he needs to buy 1800 / 50 = 36 packs of index cards. So he spends 36 * 3 = $108.

We have a 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?
And an answer: 8
So how you got the 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.
