Question: A road has four lanes, and in each lane, the number of cars is twice as many as the number of trucks in all the lanes. If there are 60 trucks in each lane, calculate the total number of vehicles in all the lanes?
Answer: If the road has four lanes and 60 trucks in each lane, the total number of trucks in all the lanes is 60 * 4 = 240. Since in each lane the number of cars is twice as many as the number of trucks in all the lanes, there are 2 * 240 = 480 cars in each lane. The total number of cars in all the lanes is 480 * 4 = 1920. In all the lanes, the total number of vehicles is 240 trucks + 1920 cars = 2160. The answer is 2160.
[Question]A movie theatre has 250 seats. The cost of a ticket is $6 for an adult and $4 for a child. The theatre is full and contains 188 children. What is the total ticket revenue for this movie session?
[Answer]The number of adults present is 250 188 = 62 adults. The revenue generated by adults is 62 * 6 = $372. The revenue generated by children is 188 * 4 = $752. So the total ticket revenue is 372 + 752 = $1124. The answer is 1124.
Q: A store has an 8% discount on all items. If Shara paid $184 for a pair of shoes, how much did Shara save?
A: The price that Shara paid is only 100% - 8% = 92% of the original price. So, every 1% is equal to $184 / 92 = $2. Therefore, Shara saved $2 x 8 = $16. The answer is 16.
Question: Marlon has a gift card for $200. He spent half of it on Monday and one-fourth of the remainder on Tuesday. How much was left on his gift card?
Answer: Since Marlon spent half of the gift card, then half of it which is $200 / 2 = $100 remained on Monday. Then on Tuesday, he spent $100 / 4 = $25. Therefore, he has $100 - $25 = $75 left in his gift card. The answer is 75.
[Question]Stephanie is moving into a new apartment. She needs to figure out how many pieces of silverware she should purchase. She needs spoons, butter knives, steak knives, and forks. For herself she figures 5 of each would be sufficient. But in case she has guests, she wants to have 10 extra pieces of each type. Then she realizes that if everything is clean at the same time, that she will have too many of everything and not enough room to fit them in her kitchen silverware drawer. So she decides to purchase 4 fewer spoons, 4 fewer butter knives, 5 fewer steak knives, and 3 fewer forks. How many pieces total of all the silverware is Stephanie going to buy?
[Answer]Stephanie wants to get 5 each of each type of silverware for herself. 5 spoons + 5 butter knives + 5 steak knives + 5 forks = 20 pieces of silverware. She wants 10 extra of each type for guests, 10 x 4 = 40. She decides to purchase less of each type. She was originally purchasing 15 of each type. 15 spoons - 4 less spoons = 11 spoons. 15 butter knives - 4 less = 11. 15 steak knives - 5 = 10. 15 forks - 3 less forks = 12. Stephanie is going to purchase 11 spoons, 11 butter knives, 10 steak knives, and 12 forks. 11 + 11 + 10 + 12 = 44. Stephanie is going to purchase 44 pieces of silverware. The answer is 44.
