How to read the watt hour meter and calculate the electricity charge

nowadays, most families are equipped with an electric energy meter. The function of installing electric energy meters at home is to accumulate the total electric energy consumed by various household appliances. The unit of measurement of electric energy meter is kW · h, which is what people used to call "degree". Kilowatt hour electricity means the electric energy consumed by an electrical appliance with a rated power of 1000 watts in one hour. The watt hour meter will run one word if it consumes one kilowatt hour. The watt hour meter is equipped with a meter, which has five readings. The first four digits in the black box represent integers, and the last digit in the red box represent decimals. For example, the indicated value of the meter of an electric energy meter is 10385, which means that the accumulated electric energy consumed by the various sensor instruments and other electric energy meters is 1038.5 degrees. Generally, the electricity charge of families is calculated on a monthly basis. Therefore, the reading of the electric energy meter should be checked every month. Checking the electric energy meter only records the integer, that is, only the number in the first four black boxes of the meter meter, not the number in the red box. The actual electricity consumption of the family in this month = the electricity meter indication of this month - the electricity meter indication of last month. Now, let's take a look at how Xiaoming's electricity bill in May is calculated. At the end of May, the indicator of the electric energy meter of Xiaoming family was 1128, and the indicator copied at the end of last month was 1038, so 1128-1038 = 90. In May, Xiaoming family shared 90 degrees of electricity. If the electricity charge per kilowatt hour is 0.4 yuan, the electricity charge payable by Xiaoming family in May is: 0.4x90 = 36 (yuan), that is, the electricity charge payable by Xiaoming family in May is 36 yuan

please calculate by yourself to see how much electricity your family uses this month

it is also very clear that the sources of funds required for the project are self owned funds and bank loans
