Question: An apartment building has 12 floors and half of them are full. The remaining floors are all at half-capacity. If each floor has 10 apartments and each apartment has four people, how many people are in the building?
Answer: Half the floors are full, so there are 12 floors * 0.5 = 6 floors that are full. So the full floors contain 6 floors * 10 apartments = 60 apartments. The remaining floors are at half - capacity, so there are 12 floors 6 full floors = 6 half - full floors. Each of these floors therefore contains 10 apartments * 0.5 = 5 apartments. So on the half - full floors, there are a total of 6 floors * 5 apartments = 30 apartments. In total, there are 30 + 60 = 90 filled apartments in the building. This means there are 90 apartments * 4 people per apartment = 360 people in the building. The answer is 360.

Question: Jude bought three chairs for his house, all at the same price. He also bought a table that costs $50 and two sets of plates at $20 for each set. After giving the cashier $130, Jude got a $4 change. How much did each of the chairs cost?
Answer: The two sets of plates amount to $20 x 2 = $40. So the table and the two sets of plates amount to $50 + $40 = $90 in all. Since Jude received a $4 change, then he paid a total of $130 - $4 = $126 for the chairs, tables, and plates. Thus, the three chairs cost $126 - $90 = $36. Therefore, each chair cost $36 / 3 = $12. The answer is 12.
