[Question]The seats of a bus are arranged in 23 rows of 4 seats. At the start, 16 people climb. At the first stop, 15 people board the bus and 3 get off. At the second stop, 17 people get on the bus and 10 get off. How many empty seats are there after the second stop?
[Answer]There are 23 * 4 = 92 seats on this bus. After the first stop, there are 16 + 15 - 3 = 28 people on the bus. After the 2nd stop, there are 28 + 17 - 10 = 35 people on the bus. So there are 92 - 35 = 57 empty seats on the bus after the 2nd stop. The answer is 57.
Q: Alexa has a lemonade stand where she sells lemonade for $2 for one cup. If she spent $20 on ingredients, how many cups of lemonade does she need to sell to make a profit of $80?

Question: On her birthday, Avianna bought red candles and blue candles in the ratio of 5:3. If Avianna had 45 red candles on her birthday, how many blue candles did she have?
Answer: If the ratio of red candles to blue candles Avianna bought was 5:3, then the total ratio was 5 + 3 = 8. If 5 represented 45 candles in the total ratio, then 8, the actual ratio, represents 8 * 45 = 360 divided by 5 is 360 / 5 = 72 candles. If the total number of candles was 72, then the number of blue candles is 72 candles - 45 candles = 27 candles. The answer is 27.
[Question]In a big box, there are marbles in 4 colors. Inside, there are 20 red marbles. There are three times more green marbles than red. Yellow marbles make up 20% of the green marbles. How many marbles are of a different color if the total of all marbles in the box is three times more than the number of green marbles?
[Answer]There are 3 * 20 = 60 green marbles. There are 60 * 20 / 100 = 12 yellow marbles. In total there are 3 * 60 = 180 marbles. That leaves 180 - 20 - 60 - 12 = 88 marbles of another color in the box. The answer is 88.
Q: Reina has three times the number of counters and four times the number of marbles as Kevin. If Kevin has 40 counters and 50 marbles, calculate the number of counters and marbles that Reina has?
A: If Kevin has 40 counters, and Reina has three, the number of counters Kevin has, Reina has 3 * 40 = 120 counters. Reina also has four times the number of marbles that Kevin has, meaning he has 4 * 50 = 200 marbles. In total, Reina has 120 counters + 200 marbles = 320 items. The answer is 320.
Question: Each of the three Morales sisters owns an orange grove that has 110 trees. Each orange tree produces medium-sized oranges. At harvest time, Gabriela's grove produced 600 oranges per tree, while Alba harvested 400 per tree. Each of Maricela's trees produced 500 oranges. With such a huge harvest, the sisters are thinking of making orange juice for sale. If it takes three medium-sized oranges to make 1 cup of juice, and then they sell each cup for $4, how much money will they make?
Answer:
Gabriela's grove produced 600 oranges / tree * 110 trees = 66000 oranges. Alba’s grove produced 400 oranges / tree * 110 trees = 44000 oranges. Maricela's trees produced 500 oranges / tree * 110 trees = 55000 oranges. The Morales sisters therefore harvested a total of 66000 oranges + 44000 oranges + 55000 oranges = 165000 oranges. The oranges will therefore yield 165000 oranges / 3 oranges / cup = 55000 cups of juice. Total sales will be 55000 cups * $4 / cup = $220000. The answer is 220000.
