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: Brenda weighs 10 pounds more than 3 times Mel's weight. If Brenda weighs 220 pounds, what is Mel's weight?
Answer: Let Mel's weight be m. Brenda’s weight is 3 * m + 10 = 220 pounds. Thus 3m = 220 - 10 = 210 pounds. Therefore Mel's weight is m = 210 / 3 = 70 pounds. The answer is 70.
[Question]Javier exercised for 50 minutes every day for one week. Sanda exercised for 90 minutes on each of three days. How many minutes did Javier and Sanda exercise in total?
[Answer]Javier = 50 * 7 = 350 minutes. Sanda = 90 * 3 = 270 minutes. Total = 350 + 270 = 620 minutes. Together Javier and Sanda exercised for 620 minutes. The answer is 620.
Q: It takes 3 men an hour to complete a job. If they are hired to work on 5 such similar jobs by a company that pays each of them $10 per hour, calculate the total amount of money the three will earn when they complete the jobs?
A: Since they are paid $10 each per hour of work and can complete a job in one hour, they earn a total of $10 * 3 = $30 together for an hour of work. If they earn together $30 for one job, for the five jobs, they'll earn $30 * 5 = $150. The answer is 150.
Question: Aubrie has four cards with the labels W, X, Y, Z printed on them. W is tagged with the number 200, X is tagged with half the number W is tagged with, Y is tagged with the total of X and W's tags and Z is tagged with the number 400. Calculate the total of all the tagged numbers.
Answer: If the card with the letter X has half the number the card with letter W has, it has 1 / 2 * 200 = 100. Together, cards with letters W and X have tags that total 100 + 200 = 300. If the card with the letter Y has the total of the numbers cards with letters, W and X have, then the total for cards with letters W, X, and Y is 300 + 300 = 600. Since the card with the letter Z has a tag of 200, the total of the numbers the tags have is 600 + 400 = 1000. The answer is 1000.
Q: Nellie can eat 12 sourball candies before crying. Jacob can only manage half of that number of candies, and Lana can only do three fewer than Jacob. They had a bucket of 30 candies, and all of them ate until they cried. If they divide the remaining candies in the bucket equally, how many sourball candies will they each get?
A:
Jacob can eat 12 / 2 = 6 candies before crying. Lana can eat 6 - 3 = 3 candies before crying. Nellie, Jacob, and Lana all ate until they cried, so they ate 12 + 6 + 3 = 21 candies. Thus, there are 30 - 21 = 9 candies left in the bucket. After dividing the remaining candies equally, they will each get 9 / 3 = 3 sourball candies. The answer is 3.
