Question: Matias is a salesman in a bookstore. He sold 7 books on Tuesday and three times as many on Wednesday. If the sales from Wednesday were tripled on Thursday, how many books did Matias sell during these three days combined?
Answer: Step-by-step reasoning process: Matias sold 7 * 3 = 21 books on Wednesday, as he sold three times more books than on Tuesday. The sales from Wednesday were tripled on Thursday, which means Matias sold then 21 * 3 = 63 books. That means in total Matias sold 7 + 21 + 63 = 91 books during these three days.
So the answer is 91.

Question: Hazel put up a lemonade stand. She sold half her lemonade to a construction crew. She sold 18 cups to kids on bikes. She gave away half that amount to her friends. Then she drank the last cup of lemonade herself. How many cups of lemonade did Hazel make?
Answer: Step-by-step reasoning process: Hazel sold 18 cups of lemonade to kids on bikes and gave half that amount, or 18 / 2 = 9 cups, away to friends. Hazel sold 18 cups + gave away 9 cups + drank 1 cup = 28 cups. Since Hazel sold half her lemonade to a construction crew, that means the 28 cups she sold to kids on bikes, gave away to friends and drank herself are the other half, so she sold 28 cups to the construction crew. In all, Hazel sold 28 + 28 = 56 cups of lemonade.
So the answer is 56.

Question: In a week, Rayman works out for half the number of hours Junior takes to work out. Wolverine, their friend, works out for twice the combined total number of hours both Rayman and Junior take during their workouts. Calculate the number of hours Wolverine takes doing her workouts if Rayman does workouts for 10 hours in a week.
Answer: Step-by-step reasoning process: If Rayman takes 10 hours doing his workouts, half the number of hours junior takes, then Junior takes 2 * 10 = 20 hours to do his workouts in a week. Altogether, Junior and Rayman take 20 + 10 = 30 hours doing their workouts in a week. Wolverine takes 2 * 30 = 60 hours to do her workouts in a week, twice the total number of hours Rayman and Junior takes.
So the answer is 60.

Question: Gary has 6 pounds of flour. He will use 4 pounds of flour to make cakes which require 0.5 pounds of flour each. The remaining 2 pounds of flour will be used to bake cupcakes, which require 1/5 pounds of flour. He plans to sell the cakes for $2.5 each and the cupcakes for $1 each in the school's bake sale. How much will Gary earn?
Answer:
Step-by-step reasoning process: Gary can bake 4 / 0.5 = 8 cakes from the 4 pounds of flour. He can bake 2 / 1 / 5 = 10 cupcakes from the 2 pounds of flour. So, he will earn $2.5 x 8 = $20 from the cakes. Hence, Gary will earn a total of $20 + $10 = $30 from baking 8 cakes and 10 cupcakes.
So the answer is 30.
