1. Need to know the conversion relationship between kWh and electricity fee.

2. The calculation method of electricity charge is related to electricity price. The relationship between electricity fee (e) and kwh can be expressed by the following mathematical formula: e equals kwh times p.

3. Where p is the electricity price per kWh, assuming that the electricity price per kWh is p = 1 yuan, the electricity price can be calculated by the above formula.

4. The calculation result is that the electricity bill is 828 yuan, so the electricity bill corresponding to 828 kWh is 828 yuan.
