Consider the Q and A. Q: Stella collects stamps. She counted 50 pages in her collector's album. There are 5 rows of 30 stamps in each of the first 10 pages of her album. The rest of the pages each have 50 stamps. How many stamps are in Stella's album?
A: 3500
What is the step-by-step reasoning process?
Step-by-step reasoning process: There are 30 x 5 = 150 stamps on each of the first 10 pages. So she has a total of 150 x 10 = 1500 stamps in the first 10 pages. There are 50 - 10 = 40 pages that have 50 stamps each. There is a total of 40 x 50 = 2000 stamps in the remaining 40 pages. Therefore, Stella has 2000 + 1500 = 3500 stamps in her album.

Consider the Q and A. Q: A pen is longer than the rubber by 3 centimeters, and shorter than the pencil by 2 centimeters. Considering the pencil is 12 centimeters long, what is the total length of the rubber, the pen, and the pencil altogether?
A: 29
What is the step-by-step reasoning process?
Step-by-step reasoning process: The pen is shorter than the pencil by 2 centimeters, so it's 12 - 2 = 10 centimeters long. That means the rubber is 10 - 3 = 7 centimeters long. So all accessories are 7 + 10 + 12 = 29 centimeters long altogether.

Consider the Q and A. Q: Tony goes on 5 rollercoasters while he is at the park. The first went 50 miles per hour. The second went 62 miles per hour. The third when 73 miles per hour. The fourth when 70 miles per hour. His average speed during the day was 59 miles per hour. How fast was the fifth coaster?
A: 40
What is the step-by-step reasoning process?
Step-by-step reasoning process: The total speed of all five coasters is 295 because 59 x 5 = 295. The final coaster went 40 miles per hour because 295 - 50 - 62 - 73 - 70 = 40.

Consider the Q and A. Q: Georgia has 25 pieces of stationery while Lorene has three times as many pieces of stationery as Georgia. How many fewer pieces of stationery does Georgia have than Lorene?
A: 50
What is the step-by-step reasoning process?
Step-by-step reasoning process:
Lorene has 25 x 3 = 75 pieces of stationery. Thus, Georgia has 75 - 25 = 50 fewer pieces of stationery than Lorene.
