How to calculate the ladder electricity bill?

1. According to the electricity bill, it can be seen that there are 750 degrees this month, of which 180 degrees is 0.56 yuan, 180 to 260 degrees is 0.6 1 yuan, and the remaining 490 degrees are 0.86 yuan. The specific calculation is as follows:

180*0.56+80*0.6 1 +(750- 180-80)*0.86

=100.8+48.8+421.4 = 571yuan.

So the total electricity bill this month is 57 1 yuan.

Second, if you don't count the electricity bill in February, the total table is 750 degrees, and the rental room is 550 degrees, then yours is: 750-550=200 degrees.

Can be calculated according to the proportion of electricity consumption:

The ratio you used =200/750=0.27. The ratio you use to rent a house is: 550/750=0.73.

According to the average monthly electricity consumption of 375 degrees in these two months, 180 degrees is 0.56 yuan per degree, 180 to 260 degrees is 0.6 1 yuan, and the rest 1 15 degrees is 0.86 yuan per degree. The specific calculation is as follows:

180 * 0.56+80 * 0.61+15 * 0.86 = 248.5 yuan.

Total electricity bill for two months: 248.5*2=497 yuan.

Therefore, it takes two months to pay the electricity fee for renting a house: 497 * 0.73 = 362.438+0 yuan.

Extended data:

The residential ladder electricity price system is another practice of promoting energy conservation and emission reduction by using price leverage. Due to historical reasons, China has long implemented the cross-subsidy system of industrial electricity price subsidizing residential electricity price.

Judging from the electricity consumption structure of residents in China, 5% of high-income families consume about 24% of electricity, which means that the welfare of low electricity price policy is more enjoyed by high-income groups. This is not conducive to social equity, but also encourages the waste of power resources.

By dividing the first, second and third grades of electricity, the price level of the third grade of electricity can be greatly improved, which can not only promote social equity, but also cultivate the awareness of saving resources and protecting the environment of the whole people and gradually develop the habit of energy conservation and emission reduction.
