Step-by-step reasoning process: There are 50 / 2 = 25 people in economy class. There are 25 people in business first and business class, so there are 25 - 3 = 22 in business class. Thus, there are 30 - 22 = 8 unoccupied seats in business class.
[Q & A] The question is A small airplane can seat 10 people in first class, 30 in business class, and 50 in economy class seating. If economy class is half full, and business class and first class have the same number of people together as economy class, how many seats are unoccupied in business class if only three people on the flight have first class seats?
The answer is 8

Step-by-step reasoning process: First quadruple the price of the wallet: $22 * 4 = $88. Then subtract $3 to find the cost of the purse: $88 - $3 = $85. Then add the price of the wallet and purse to find the total cost: $85 + $22 = $107.
[Q & A] The question is Carly is thinking about buying a wallet that costs $22 and a purse that costs $3 less than four times the cost of the wallet. What is the combined cost of both items?
The answer is 107

Step-by-step reasoning process: Kylie makes 10 + 2 = 12 beaded necklaces. The number of beads used for the necklaces is 12 * 20 = 240 beads. The number of beads used for the bracelets is 5 * 10 = 50 beads. The number of beads used for the earrings is 7 * 5 = 35 beads. The total number of beads used is 240 + 50 + 35 = 325 beads.
[Q & A] The question is Kylie makes 10 beaded necklaces on Monday and 2 beaded necklaces on Tuesday. Then Kylie makes 5 beaded bracelets and 7 beaded earrings on Wednesday. 20 beads are needed to make one beaded necklace. 10 beads are needed to make one beaded bracelet. 5 beads are needed to make one beaded earring. How many beads does Kylie use in total to make her jewelry?
The answer is 325

Step-by-step reasoning process: In the full decks, John has a total of 52 cards in a full deck of cards * 3 full decks of cards = 156 cards. A half - full deck of cards contains 52 cards in a full deck of cards / 2 = 26 cards. So from the half - full decks, John has a total of 26 cards * 3 half - full decks = 78 cards. This is a total of 156 cards from full decks + 78 cards from half - full decks = 234 cards. After throwing some in the trash, he now holds a total of 234 cards - 34 trashed cards = 200 cards.
[Q & A]
The question is John is holding a poker night with his friends and is getting the decks of cards ready before his friends show up. After losing so many cards from various decks, John thinks he needs to count exactly how many cards he has to make sure he has enough full decks for the night. Each deck of cards should hold 52 cards. He finds 3 half-full decks of cards and 3 full decks of cards. As he is arranging them, he realizes that the quality of a lot of the cards is quite poor and decides to throw 34 of the cards in the trash. How many cards does John now have?
The answer is 200
