[Question]The population of Mojave was 4000 a decade ago. If the town's population has increased three times, and the population analysis firm predicts that it will increase by 40% after five years, how many people will be in Mojave in five years?
[Answer]Since the population of Mojave has increased three times the number it was a decade ago, there are 3 * 4000 = 12000 people in Mojave now. It's predicted that the population will increase by 40 / 100 * 12000 = 4800 people after five years. This means there will be 12000 + 4800 = 16800 people living in Mojave in five years. The answer is 16800.
Q: A new condo development has 23 floors. Regular floors have 12 units, whereas penthouse floors have only 2 units. If the top 2 floors are assigned for penthouse units, how many units does this condo have in total?
A: If the condo has 23 floors and the top 2 floors are reserved for penthouse then there are 23 - 2 = 21 floors for regular units. If a regular floor has 12 units each, then 21 regular floors would have 12 * 21 = 252 units. If a penthouse floor has 2 units each, then 2 penthouse floors would have 2 * 2 = 4 units. The total units in the property would then be 252 regular + 4 penthouse or 252 + 4 = 256 units. The answer is 256.
Question: Tom buys 20 shares of a stock that costs $3 each. He sells 10 of those shares for $4 each. The rest of the shares end up doubling in value. How much profit does he make?
Answer: He spends 3 * 20 = $60 on the shares. He sells 10 for 10 * 4 = $40. He sells the other 20 - 10 = 10 for a higher valuation. Their price was 3 * 2 = $6. So he got 10 * 6 = $60 from those. So in total, he got 60 + 40 = $100. So his profit was 100 - 60 = $40. The answer is 40.
[Question]James listens to super-fast music. It is 200 beats per minute. He listens to 2 hours of music a day. How many beats does he hear per week?
