Question: Taro and Vlad play a video game competition together, earning 5 points for every win. After playing 30 rounds, Taro scored 4 points less than 3/5 of the total points scored. How many total points did Vlad score?
Answer: Step-by-step reasoning process: If they played 30 rounds, the total possible points from wins are 5 * 30 = 150 points. Scoring 3 / 5 of the total possible points earns you 3 / 5 * 150 points = 90 points. If Taro scored 4 points less than 3 / 5 of the total points, he scored 90 points - 4 points = 86 points. If the total points scored in the game is 150, then Vlad scored 150 points - 86 points = 64 points.
So the answer is 64.

Question: In the city, there is a block of flats. This block has 12 floors. Half of the floors have 6 apartments and the other half have 5 apartments. One apartment can accommodate a maximum of 4 residents. What is the maximum number of residents that can live in this block of flats?
Answer: Step-by-step reasoning process: Half of the floors have different numbers of apartments. Half the number of floors is 12 floors / 2 = 6 floors. One half of the block consists of 6 floors * 6 apartments / floor = 36 apartments. And the other half consists of 6 floors * 5 apartments / floor = 30 apartments. There are 30 + 36 = 66 apartments on all floors in the block. All the apartments can therefore accommodate 66 apartments * 4 residents / apartment = 264 residents.
So the answer is 264.

Question: Wendy went to the dentist for a cleaning, two fillings, and a tooth extraction. The dentist charges $70 for a cleaning and $120 for a filling. Wendy’s dentist bill was five times the cost of a filling. What did Wendy pay for the tooth extraction?
Answer: Step-by-step reasoning process: Wendy’s dentist bill was 5 * $120 = $600. She got two fillings at a cost of 2 * $120 = $240. Thus, Wendy paid $600 - $240 - $70 = $290 for the tooth extraction.
So the answer is 290.

Step-by-step reasoning process: He burns 2 * 300 = 600 calories an hour. He dances for .5 * 2 = 1 hour per day. So he burns 600 * 1 = 600 calories per day. So he burns 600 * 4 = 2400 calories per week.
So the answer is 2400.
