Solution: (1) 256 million = 256 million.

The tourism income of urban areas and county towns is X million yuan and Y million yuan respectively.

Equations can be listed according to the meaning of the question.

x+y=25600

X divided by (80* 40%)-Y divided by (80* 60%) = 50.

solve an equation

X= 1 1200 (ten thousand yuan)

Y= 14400 (ten thousand yuan)

A: Omit.

(2) If the per capita tourism consumption of tourists in 2008 is Z compared with that in 2007, the percentage of total tourism revenue is 2.59z, and the percentage of tourists is1.5z.

According to the meaning of the question, you can list the equations.

(25600 divided by 80) (1+z) × 80 (1+1.5z) = 25600 (1+2.59z).

Simplify the arrangement: 1.5z2-0.09z=0, and get the solution: z=0.06 or z=0 (discard).

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).

It's done.
