There are two kinds of math emergencies in hotel rooms: triple rooms and double rooms.
Answer: There are 8 triple rooms, and the double room 13 is set to triple room X, so the double room is (50-3X)/2. Because it is 50% off, there is an equation: 75x+(50- 3x)/2 * 70 =1510 75x is three people's money, 50-. After simplification, we get: 3X=240, so X=8 (50-3X)/2= 13, which we hope to adopt.
