Answer the following question.
Ellie takes her little brother down to the pond to teach him how to skip stones. After he takes his first throw, she gives him pointers to improve his technique. His second throw skips two more times across the water than his first. His third throw skips twice as many times as his second. His fourth throw skips 3 fewer times than his third throw. His fifth throw skips one more time than the fourth throw. If his fifth throw skipped 8 times across the water, how many skips did he make in total between all of his throws?
Step-by-step reasoning process: His fourth throw made 8 - 1 = 7 skips. His third throw made 7 + 3 = 10 skips. His second throw made 10 / 2 = 5 skips. His first throw made 5 - 2 = 3 skips. The total number of skips is 8 + 7 + 10 + 5 + 3 = 33 skips.
The answer is 33.

Answer the following question.
Bill is a painter who is hired to paint a client’s house. The house has three bedrooms, and twice as many other rooms as bedrooms. The client wants each bedroom painted a different color, and the other rooms painted white. Each room takes 2 gallons of paint. Color paint comes in 1-gallon paint cans, and white paint comes in 3-gallon cans. How many cans of paint will Bill need for the whole house?
Step-by-step reasoning process: Bill needs 2 * 3 = 6 gallons of color paint for the 3 bedrooms. Thus, he needs 6 / 1 = 6 cans of color paint for the bedrooms. There are 2 * 3 = 6 other rooms in the house. He needs 2 * 6 = 12 gallons of white paint for the other rooms. Thus, he needs 12 / 3 = 4 cans of white paint. In all, Bill needs 4 + 6 = 10 cans of paint for the whole house.
The answer is 10.

Answer the following question.
Harry is ordering pizza. A large pizza is 14. It costs $2 per topping. He orders 2 large pizzas, each with 3 toppings. He then adds a 25% tip. What is the total cost?
Step-by-step reasoning process: The toppings on each pizza are $6 because 3 x 2 = 6. The total for each pizza is $20 because 14 + 6 = 20. The pizzas cost $40 because 2 x 20 = 40. The tip is $10 because 40 x .25 = 10. The total is $50 because 40 + 10 = 50.
The answer is 50.
