Answer the following question.
Autumn was constantly misplacing her pencils. At the start of the school year, she purchased a pack of 20 pencils. In the first month of school, she misplaced 7 pencils, broke 3 pencils and had to throw them away, she found 4, and bought 2. How many pencils did Autumn have left?
Step-by-step reasoning process: Autumn misplaced 7 and broke 3, so that lost her 7 + 3 = 10 pencils. Autumn found 4 pencils and bought 2, so she gained 4 + 2 = 6 pencils. She started with 20 pencils, lost 10 and gained 6 so she had 20 - 10 + 6 = 16 pencils left.
The answer is 16.

Answer the following question.
Joey needs to take a new prescription. The first day he needs to take one pill. Each day he must take two more pills than the previous day. How many pills will he take in a week?
Step-by-step reasoning process: For the second day he takes 1 + 2 = 3 pills. For the third day he takes 3 + 2 = 5 pills. For the fourth day he takes 5 + 2 = 7 pills. For the fifth day he takes 7 + 2 = 9 pills. For the sixth day he takes 9 + 2 = 11 pills. For the seventh day he takes 11 + 2 = 13 pills. For the entire week he takes a total of 1 + 3 + 5 + 7 + 9 + 11 + 13 = 49 pills.
The answer is 49.

Answer the following question.
Billy has 8 hours of free time on each day of the weekend. He wants to spend 75% of his time playing video games and the rest of his time reading. He can read 60 pages an hour and his books all contain 80 pages. How many books does he read?
Step-by-step reasoning process: He has 16 hours because 2 x 8 = 16. He is going to spend 25% of his time reading because 100 - 75 = 25. He has 4 hours to read because 16 x .25 = 4. He will read 240 pages because 4 x 60 = 240. He will read 3 books because 240 / 80 = 3.
The answer is 3.

Answer the following question.
On Tuesday, a fruit vendor sold 2.5 dozen lemons and 5 dozens avocados. What is the total number of fruits that the fruit vendor sold?
Step-by-step reasoning process: Since 1 dozen is equal to 12, then the vendor sold 2.5 x 12 = 30 lemons. While he sold 5 x 12 = 60 avocados. So, the fruit vendor sold a total of 30 + 60 = 90 fruits.
The answer is 90.
