A hotel room department has 60 rooms for tourists to live in. When the price of each room is 200 yuan per day, the room can be full. When the price of each room is increased by 10 yuan per day, there will be a room free. For a room with tourists, the hotel needs to pay 20 yuan per day for each room. Suppose the price of each room is increased by X yuan per day The functional relationship between the daily occupancy y (rooms) and X (yuan); (2) the functional relationship between the daily room charge P (yuan) and X (yuan); (3) the functional relationship between the daily profit w (yuan) and X (yuan) of the room department of the hotel; when the price of each room is how many yuan per day, w has the maximum value? What is the maximum value?

(1) From the question meaning: y = 60-x10 (2 points) (2) z = (200 + x) (60-x10) = - 110x2 + 40x + 12000 (3 points) (3) w = (200 + x) (60-x10) - 20 × (60-x10) (2 points) = - 110x2 + 42x + 10800 = - 110 (x-210) 2 + 15210. When x = 210, w has the maximum value

What is the simple calculation method of 32 x 0.65 + 3.2 x 3.5 and 1.8 x 0.62 + 0.18 x 3.9 - 0.018?
In a hurry

32 X 0.65 + 3.2 X 3.5
=32 X 0.65 + 32 X 0.35
=32x（0.65+0.35）
=32x1
=32
1.8 X 0.62 + 0.18 X 3.9 - 0.018
=1.8 X 0.62 + 1.8 X 0.39 - 1.8 x0.01
=1.8x（0.62+0.39-0.01）
=1.8x1
=1.8

The steps of adding, subtracting and eliminating elements to solve quadratic equation of two variables
Be concise and clear

1. Simplifying equations
All of them should be in the form of AX + by = C
2. Observe the coefficient of the unknowns and select the unknowns to be eliminated
3. After selecting the unknowns, find out the least common multiple of the unknowns. If the sign of the coefficients of the unknowns is opposite, then the two equations are added to eliminate the unknowns; if the sign is the same, subtract to eliminate the unknowns
The system of equations is reduced to a linear equation with one unknown
4. Solve the linear equation of one variable and get the value of an unknown number
5. The value of the unknowns is substituted into an equation of the original system of equations to solve two unknowns
6. Suggestion: check, this can no longer be done in writing, check on the draft paper, is the solution of the equations
