Uncle Zhao's house used 250 degrees of electricity in March and April, and the peak-valley ratio was 2: 3. How much electricity does Uncle Zhao need to pay in March, April and February?
Peak power consumption: 250*2/5= 100 kwh, and peak power consumption: 0.55* 100=55.00 yuan.
Electricity consumption in the valley: 250- 100= 150 kWh, and electricity charge in the valley: 0.35* 150=52.50 yuan.
Zhao Xiaodi needs to pay the electricity fee of 55.00+52.50 = 107.50 yuan for three or four months.
