To understand this problem, we must first understand that electricity charge = price per kilowatt-hour x total kilowatt-hour, so we started (1). Because May is the original electricity price, the electricity consumption in May = May electricity charge ÷ original electricity price = 48 x (degrees). In June, the price per kWh increased by 10%. Therefore, the electricity consumption per kwh in June should be x( 1+ 10%), and the electricity consumption in June =66÷x( 1+ 10%) (kwh). (2) According to the conditions, June is 20 kWh more than May, so June. The result is: x=0.6. People asked about the adjusted electricity price, so 0.6X 1. 1=0.66 (yuan). Dude, this result is detailed enough. Thank you. Please give points.
