Question: Trevor and two of his neighborhood friends go to the toy shop every year to buy toys. Trevor always spends $20 more than his friend Reed on toys, and Reed spends 2 times as much money as their friend Quinn on the toys. If Trevor spends $80 every year to buy his toys, calculate how much money in total the three spend in 4 years.
Answer: Step-by-step reasoning process: If Trevor spends $20 more than Reed every year to buy toys, Reed spends $80 - $20 = $60. Since Reed uses $60 every year to buy toys, his friend Quinn uses 60 / 2 = $30 every year to buy toys. The total amount of money the three spend in a year together to buy toys is $30 + $60 + $80 = $170. The total amount of money the three will use to buy toys in 4 years is $170 * 4 = $680.
So the answer is 680.

Question: Steve is building a bench for the playground and needs 6 lengths of wood that measure 4 feet and 2 lengths of wood that measure 2 feet. How many feet of wood does Steve need to buy?
Answer: Step-by-step reasoning process: Steve needs 6 lengths of 4 feet of wood or 6 x 4 = 24 feet of wood. He also needs 2 lengths of 2 feet of wood or 2 x 2 = 4 feet of wood. Altogether, Steve needs 24 feet of wood + 4 feet of wood = 28 feet of wood.
So the answer is 28.

Question: Mary brought 50 stickers to class. She gave 4 stickers to each of her 5 friends. She gave everyone else in class two stickers each. If she has 8 stickers left over, how many students are in the class, including Mary?
Answer: Step-by-step reasoning process: She gave out 50 - 8 = 42 stickers in total. She gave 4 * 5 = 20 stickers to her friends. She gave out 42 - 20 = 22 stickers to the rest of the class. This means there are 22 / 2 = 11 other students in the class. There are a total of 1 + 5 + 11 = 17 students in the class.
So the answer is 17.
