Q: A movie ticket costs $5. The cost of the popcorn is 80% of the cost of the ticket and a can of soda costs 50% of the cost of the popcorn. A family bought 4 tickets, 2 sets of popcorn, and 4 cans of soda. How much did they spend?
A: The cost of the popcorn is $5 x 80 / 100 = $4. The cost of a can of soda is $4 x 50 / 100 = $2. The cost of 4 tickets is $5 x 4 = $20. The cost of 2 sets of popcorn is $4 x 2 = $8. The cost of 4 cans of soda is $2 x 4 = $8. Therefore, the family paid a total of $20 + $8 + $8 = $36. The answer is 36.

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.

Q: The trip from Philip's house to the children's school is 2.5 miles, and the trip to the market is 2 miles. He makes the round trip to school two times (when taking the children to school and when bringing them back) every day for 4 days a week. Then he makes a round trip to the market once during weekends. What is his car's mileage for a typical week?
A:
Making the round trip to school means driving from the house to school and then back, for a total of 2.5 + 2.5 = 5 miles. He makes this trip twice in one day for a total of 2 * 5 = 10 miles. He does this 4 times in a week for a total of 4 * 10 = 40 miles. The round trip (once a week) to the market is 2 + 2 = 4 miles. His total mileage for a typical week = 40 + 4 = 44 miles. The answer is 44.
