Manhattan Prep
Every attendee at a monster truck rally paid the same admission fee. How many people attended the rally?
1) If the admission fee had been raised to $20 and twice as many people had attended, the total admission fees collected would have been three times greater
2) If the admission fee had been raised to $30 and two-thirds as many people had attended, the total admission fees collected would have been 150% of the actual admission fees collected
