Question: Daniel has a collection of 346 video games. 80 of them, Daniel bought for $12 each. Of the rest, 50% were bought for $7. All others had a price of $3 each. How much did Daniel spend on all the games in his collection?
Answer: Step-by-step reasoning process: On 80 games, Daniel spend 80 games * $12 / game = $960. The rest of the collection is 346 games - 80 games = 266 games. 50% of these games means 50 / 100 * 266 games = 133 games. Daniel bought them for $7 each, so he had to spend 133 games * $7 / game = $931 on them. The other 133 games were bought for $3 each, so they've cost him 133 games * $3 / game = $399. On all games in total Daniel spent $960 + $931 + $399 = $2290.
So the answer is 2290.

Question: On Monday a group of 7 children and 5 adults went to the zoo. On Tuesday a group of 4 children and 2 adults went as well. Child tickets cost $3, and adult tickets cost $4. How much money did the zoo make in total for both days?
Answer: Step-by-step reasoning process: The total amount of children that went on both days is 7 + 4 = 11. The cost of the children's tickets is 11 $3 = $33. The total amount of adults that went on both days is 5 + 2 = 7. The cost of the adults' tickets is 7 $4 = $28. The zoo made $33 + $28 = $61 in total.
So the answer is 61.

Question: The Science museum sells dinosaur models for $100 each. A certain school bought 2 models for the kindergarten library and also bought twice as many for the elementary library. Since the school bought more than 5 models, there was a 5% reduction in price for each model. How much did the school pay in all?
Answer: Step-by-step reasoning process: The school bought 2 x 2 = 4 dinosaur models for the elementary library. So the school bought a total of 2 + 4 = 6 models. The price of each model was reduced by $100 x 5 / 100 = $5. Thus, each model cost $100 - $5 = $95. Therefore, the school paid a total of $95 x 6 = $570.
So the answer is 570.

Question: Carla is dividing up chores for her two kids, Anna and Billy. She wants each of them to spend the same number of minutes working. Sweeping takes 3 minutes per room, washing the dishes takes 2 minutes per dish, and doing laundry takes 9 minutes per load. If Anna does the sweeping for 10 rooms and Billy does two loads of laundry, how many dishes should Billy wash so they spend the same amount of time doing chores?
Answer:
Step-by-step reasoning process: First find the total time Billy spends on laundry: 2 loads * 9 minutes / load = 18 minutes. Then find the total time Anna spends sweeping: 3 minutes / room * 10 rooms = 30 minutes. Then find how much longer Anna has already worked than Billy: 30 minutes - 18 minutes = 12 minutes. Then divide the difference in work time by the time to wash one dish to find the number of dishes Billy has to wash to work the same amount of time as Anna: 12 minutes / 2 minutes / dish = 6 dishes.
So the answer is 6.
