Leo's assignment was divided into three parts. He finished the first part of his assignment in 25 minutes. It took him twice as long to finish the second part. If he was able to finish his assignment in 2 hours, how many minutes did Leo finish the third part of the assignment? Give the rationale and then the answer.
Let's think step by step. It took Leo 25 x 2 = 50 minutes to finish the second part of the assignment. Leo finished the first and second parts of the assignment in 25 + 50 = 75 minutes. He finished the entire assignment in 60 x 2 = 120 minutes. Therefore, it took Leo 120 - 75 = 45 minutes to finish the third part of the assignment.. The answer is: 45.

Aunt Angela has 70 jellybeans in a jar. She wants to divide them equally and give them to her 3 nephews and 2 nieces. How many jellybeans did each nephew or niece receive? Give the rationale and then the answer.

Mary goes with her 3 children to the circus. Tickets cost $2 for adults and $1 for children. Mary pays with a $20 bill. How much change will she receive? Give the rationale and then the answer.
Let's think step by step. Mary's ticket costs $2 / ticket * 1 ticket = $2. Mary's children's tickets cost 3 tickets * $1 = $3. Together the tickets cost $2 + $3 = $5. After paying with a 20 - dollar bill, Mary will receive $20 - $5 = $15.. The answer is: 15.
