Unreasonable. The electricity bill should be calculated by degrees, not by a fixed amount. Therefore, it is not reasonable to only receive electricity from 0.7 yuan. In addition, there is also a problem in the way of increasing the power loss in 0.8 yuan, because the size of the power loss should be related to factors such as the size of the house, the use of electrical appliances, the quality of wires and so on, rather than being calculated according to a fixed amount.
