Q: Five adults and two children go to see a movie and buy $12 worth of concessions. The total cost of their trip is $76. If each child's ticket is $7, how much, in dollars, are the adult tickets?
A: First take out the cost of the concessions. That leaves $76 - $12 = $64 for the movie tickets. Each child ticket costs $7, so two children's tickets cost $7 per child ticket * 2 child tickets = $14. To find the amount spent on adult tickets, subtract the cost of the children's tickets to get $64 - $14 = $50 for adult tickets. Divide $50 for adult tickets / 5 adults = $10 per adult ticket. The answer is 10.

Q: Palmer loves taking photos and has an album of 100 photos under her bed to mark memories of places she's been. She recently went on a long trip to Bali. Palmer took 50 new pictures in the first week and twice that many in the second week. She was running out of space at the end of her trip and took only 80 new photos total across the third and fourth weeks. If she adds the pictures from Bali to her collection, how many total photos does Palmer have under her bed now?
A: While in Bali, Palmer took 50 pictures in the first week and thus 2 * 50 photos = 100 photos in the second week. The total number of photos she took in Bali is 50 photos on the first week + 100 photos on the second week + 130 photos = 280 photos. When she adds the photos she from Bali to her album, Palmer has a total of 280 + 100 = 380 photos. The answer is 380.

Q: Half of Taylor's house guests like weak coffee and the other half like strong coffee in the morning. Taylor uses 1 tablespoon of coffee per cup of water to make it weak and he doubles that amount to make it strong. If he makes 12 cups of both weak and strong coffee, how many tablespoons of coffee will he need?
A:
He uses 1 tablespoon for weak coffee and doubles that for strong so the strong uses 1 * 2 = 2 tablespoons. For the weak coffee he uses 1 tablespoon per 1 cup of water and he needs to make 12 cups so he'll use 1 * 12 = 12 tablespoons. For the strong coffee he uses 2 tablespoons per 1 cup of water and he needs to make 12 cups so he'll use 2 * 12 = 24 tablespoons. All total he will use 12 tablespoons for the weak coffee and 24 tablespoons for the strong coffee for a total of 12 + 24 = 36 tablespoons. The answer is 36.
