Question: Carly is overnight shipping some fresh-baked cookies to her grandma. The shipping cost is equal to a flat $5.00 fee plus $0.80 per pound of weight. If the package weighs 5 pounds, how much does Carly pay for shipping?
Answer: Step-by-step reasoning process: First calculate the weight - based charge by multiplying the package's weight in pounds by the price per pound: 5 pounds * $0.80 / pound = $4.00. Then add the weight - based charge to the flat fee to find the total cost: $4.00 + $5.00 = $9.00.
So the answer is 9.

Question: Mark buys a Magic card for $100, which then triples in value. How much profit would he make selling it?

So the answer is 200.

Question: The kindergartners each need to bring one mini tissue box to class for the school year. There are three kindergartner groups with 9, 10, and 11 students respectively. Each mini tissue box contains 40 tissues. How many tissues do the kindergartner groups bring together?
Answer: Step-by-step reasoning process: There are a total of 9 + 10 + 11 = 30 kindergartners. Altogether, they bring a total of 30 x 40 = 1200 tissues.
So the answer is 1200.

Question: 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?
Answer:
Step-by-step reasoning process: 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.
So the answer is 5.
