Assuming that the per capita consumption of each district and county is X yuan, then
480000 * X+320000 *(50+X)= 256000000
X=300 yuan. County income is 3 million * 480,000 = 65,438+44 million yuan.
Urban income is 350 * 320,000 =1.1.200 million yuan.
(2) Per capita consumption in 2007 was 256 million yuan/800,000 people =320 yuan/person.
Assuming that the per capita consumption in 2008 increased by y compared with that in 2007, then:
The number of people has increased by1.5y.
The proportion of total revenue increased by 2.59% year-on-year.
In 2008, the per capita consumption was 320*( 1+Y) yuan.
The number of passengers is 80*( 1+ 1.5Y) million.
The total income is 25,600 * (1+2.59y) million yuan.
Equation: 25600 * (1+2.59y) = [320 * (1+y)] * [80 * (1+1.5y)]
1+2.59Y =( 1+Y)*( 1+ 1.5Y)
Y=0.06=6%
The income in 2008 is: 2.56*( 1+2.59*0.06).
=2.56* 1. 1554
= 296 million yuan
