Question: Jessica wrote a long letter to her aunt and needed to put stamps on it to mail it. She used eight pieces of paper that weigh 1/5 of an ounce each, and her envelope weighs 2/5 of an ounce. She needed one stamp per ounce. How many stamps did Jessica need to mail her letter?
Answer: Jessica’s papers weigh 8 * 1 / 5 = 8 / 5 ounces. The papers in the envelope weigh 8 / 5 + 2 / 5 = 10 / 5 = 2 ounces. Thus, Jessica needs 2 * 1 = 2 stamps to mail her letter. The answer is 2.
[Question]Tom decided to go on a trip. During this trip, he needs to cross a lake, which in one direction takes 4 hours. During this time, Tom needs an assistant to help him with the crossing. Hiring an assistant costs $10 per hour. How much would Tom have to pay for help with crossing the lake back and forth?
[Answer]Crossing the lake two times (back and forth) would take 4 * 2 = 8 hours. So Tom would need to pay an assistant 8 * 10 = $80. The answer is 80.
Q: To run his grocery store, Mr. Haj needs $4000 a day. This money is used to pay for orders done, delivery costs and employees' salaries. If he spends 2/5 of the total operation costs on employees' salary and 1/4 of the remaining amount on delivery costs, how much money does he pay for the orders done?
A: The total amount of money Mr. Haj used to pay for employee salary is 2 / 5 * $4000 = $1600. After paying the employee salaries, Mr. Haj remains with $4000 - $1600 = $2400. He also uses 1 / 4 * $2400 = $600 on delivery costs. The remaining amount of money that he uses to pay for orders is $2400 - $600 = $1800. The answer is 1800.
Question: Hanna has $300. She wants to buy roses at $2 each and give some of the roses to her friends, Jenna and Imma. Jenna will receive 1/3 of the roses, and Imma will receive 1/2 of the roses. How many roses does Hanna give to her friends?
Answer: Hanna can buy $300 / $2 = 150 roses. So, Jenna will receive 1 / 3 x 150 = 50 roses. While Imma will receive 1 / 2 x 150 = 75 roses. Therefore, Hanna gives a total of 50 + 75 = 125 roses to her friends. The answer is 125.
[Question]Walmart sells a multitool with a screwdriver, 3 knives, and two other tools. Target sells a multitool with a screwdriver, twice as many knives as Walmart, three files and a pair of scissors. How many more tools does the Target multitool have compared to Walmart?
[Answer]First find the total number of tools in the Walmart multitool: 1 tool + 3 tools + 2 tools = 6 tools. Then find the total number of knives in the Target multitool: 3 knives * 2 = 6 knives. Then find the total number of tools in the Target multitool: 1 tool + 6 tools + 3 tools + 1 tool = 11 tools. Then subtract the number of tools in the Walmart multitool from the number in the Target multitool to find the difference: 11 tools - 6 tools = 5 tools. The answer is 5.
