Q: Alina and her best friend Lucia like to chat a lot. On a particular day, Alina sent 20 fewer messages than her friend Lucia, who sent 120 messages. The next day, Lucia sent 1/3 of the messages she sent the previous day, while Alina doubled the messages she sent on the first day. If they sent the same number of messages on the third day as the first day, what is the total number of messages they sent in those three days?
A: On the first day, Alina sent 120 - 20 = 100 messages. The total number for the first day is 100 + 120 = 220 messages. On the second day, Lucia sent 1 / 3 * 120 = 40 messages. Alina sent 100 * 2 = 200 messages on the second day. The total for the second day is 40 + 200 = 240 messages. For the three days, they sent 220 + 220 + 240 = 680 messages. The answer is 680.

Q: Shonda is throwing an Easter egg hunt for her 2 kids and their 10 friends. She is also supplying enough eggs for herself and the 7 other adults there to find eggs as well. If there are 15 Easter egg baskets for everyone to share and each ends up holding 12 Easter eggs, when they equally distribute all of the Easter eggs to everyone, how many eggs does each person get?
A: There are 15 Easter egg baskets with 12 Easter eggs in them, 15 x 12 = 180 Easter eggs. There are 7 adults + Shonda (1) + 2 of Shonda's kids + 10 of their friends = 20 people at the Easter egg hunt. There are 180 Easter eggs for 20 people, 180 / 20 = 9 Easter eggs each for everyone. The answer is 9.

Q: An elevator is on the 9th floor. It goes down 7 floors, then up 3 floors, then up 8 floors. If the elevator is on the top floor, how many floors are there in the building?
A:
From the 9th floor, the elevator went down to the 9 - 7 = 2nd floor. Then went up to the 2 + 3 = 5th floor. Then, went up to the 5 + 8 = 13th floor; hence there are 13 floors in the building. The answer is 13.
