Q: Hannah has three brothers. Her brothers are all 8 years old. How old is Hannah if she is twice as old as the sum of her brother's ages?
A: The total of Hannah's brothers' ages is 3 * 8 = 24. Hannah is twice as old as the total of her brothers' ages, so Hannah is 24 * 2 = 48 years old. The answer is 48.
Question: Michelle is bringing sandwiches to work to give to her co-workers. She gives 4 sandwiches to one of her co-workers and keeps twice this amount for herself. If she had originally made 20 sandwiches, how many sandwiches does she have left to give to her other co-workers?
Answer: Michelle kept 4 sandwiches * 2 = 8 sandwiches for herself. This leaves 20 total sandwiches – 4 sandwiches for a coworker – 8 sandwiches for herself = 8 sandwiches for her other co - workers. The answer is 8.
[Question]Big Joe is the tallest player on the basketball team. He is one foot taller than Ben, who is one foot taller than Larry, who is one foot taller than Frank, who is half a foot taller than Pepe. If Pepe is 4 feet six inches tall, how tall is Big Joe, in feet?
[Answer]Four feet six inches is the same as 4.5 feet tall. If Frank is 0.5 feet taller than Pepe, then he is 4.5 + 0.5 = 5 feet tall. If Larry is one foot taller than Frank, then he is 5 + 1 = 6 feet tall. If Ben is one foot taller than Larry, then he is 6 + 1 = 7 feet tall. If Big Joe is one foot taller than Ben, then he is 7 + 1 = 8 feet tall. The answer is 8.
Q: Marissa is serving her kids lunch. Each kid gets a burger with 400 calories and 5 carrot sticks with 20 calories each, and some cookies with 50 calories each. Marissa wants each kid to eat a total of 750 calories for lunch. How many cookies does each kid get?
A: First figure out how many total calories come from the carrots by multiplying the calories per carrot by the number of carrots: 20 calories / carrot * 5 carrots = 100 calories. Then subtract the calories the kids have already eaten from the goal number of calories to find out how many more total calories they should eat: 750 calories - 400 calories - 100 calories = 250 calories. Then divide the total number of calories by the calories per cookie to find the number of cookies each kid gets: 250 calories / 50 calories / cookie = 5 cookies. The answer is 5.
Question: Sabrina is collecting herbs to make a poultice for her grandmother. She needs twice as many basil leaves as sage leaves and 5 fewer sage leaves than verbena leaves. If she needs 12 basil leaves, how many leaves total does she need?
Answer: First find the number of sage leaves Sabrina needs: 12 basil / 2 basil / sage = 6 sage. Then add 5 to find the total number of verbena leaves she needs: 6 sage + 5 = 11 verbena. Finally, add up all the different leaves to find the total number: 6 sage + 11 verbena + 12 basil = 29 leaves. The answer is 29.

Maria wants to pay 3 * 20 = $60 for the canvas. Maria needs 5 liters of paint, so the cost of it would be 8 * 5 = $40. So in total Maria will earn 200 - 40 - 60 - 20 = $80 if she will be able to sell the painting at the mentioned price. The answer is 80.
