Represent the electricity bill using a linear equation in 2 variables with respect to fixed charge and unit consumption in the month of April 2020, May 2020 and December 2019. Find the reason behind the variation of electricity bill explaining the use of different electric appliances. April bill -385 May bill - 395 December bill-275
