It is reported that Yichang received about 800,000 tourists during the May 1 Golden Week in 2007, and the total tourism revenue was about 256 million yuan, including the number of tourists received by counties. Solution: (1) 256 million = 256 million,

Assuming that the tourism income of the urban area and the county is X million yuan and Y million yuan respectively, the equation can be listed according to the meaning of the question:

, solutions,

A: The tourism income of urban areas and counties (cities) is1120,000 yuan and1440,000 yuan respectively.

(2) Suppose that the growth percentage of per capita tourism consumption in 2008 is Z compared with that in 2007,

Then the percentage of total tourism revenue growth is 2.59z, and the percentage of tourists growth is1.5z.

According to the meaning of the question, the equation can be listed: (1+z) × 80 (1+1.5z) = 25600 (1+2.59z).

Simplified arrangement: 1.5z 2 -0.09z=0,

Solution: z=0.06 or z=0 (truncation)

In 2008, Yichang's "May Day" Golden Week tourism revenue was:

25600 (1+2.59z) = 25600× (1+0.1554) = 29578.24 (ten thousand yuan) = 2957824 (one hundred million yuan) ≈ 296 (one hundred million yuan).

A: It is estimated that the city's total tourism revenue in the May 1 Golden Week in 2008 will be 296 million yuan.
