The annual electricity consumption of a certain place was 0.8 yuan, The annual electricity price of a place is 0.8 yuan / kWh, and the annual electricity consumption is 100 million kwh. This year, the electricity price is planned to be adjusted to 0.55-0.75 yuan. According to calculation, if the electricity price is adjusted to X Yuan, the new electricity consumption of this year is y billion kWh and (x-4) is in inverse proportion, and when x = 0.65 yuan, y = 0.8 (1) Find the functional relationship between Y and X; (2) When the electricity price is adjusted to 0.6 yuan / kWh, what is the electricity consumption in this year

There seems to be something wrong with this problem... It should be x-0.4
But this can also be done
1. The new electricity consumption is y billion kwh, which is in inverse proportion to (x-4)
Then y = K / (x-4)
Take x = 0.65, y = 0.8 into the equation
8 = K / (0.65-4)
k=-2.68
The equation is y = 2.68 / (4-x)
