Ask a math question and make a list.
Solution: If each bed is increased by 2x yuan, the rented bed is: 100- 10x, and the rent is: (100-10x) (10+2x).
If you charge Y yuan every day, there is a function: Y = (100-10x) (10+2x), that is, y=-20x? + 100x+ 1000
When x=- 100/(-2*20)=2.5, y has a maximum value, which is: 1 125.
So the daily charge for each bed is 10+2*2.5= 15 (RMB).
