The second company has a contract that requires and initial deposit of $50 and charges $20. a) Considering that Chela's household averages about 1200 kilowatt, which company would be best for her? b) For what kilowatt usage would the companies be the same price? c) Due to an influx of usage in electricity both companies must raise their rates. Assuming that the initial deposit remains the same for both companies What would the new rate have to be so that a usage of 2000 kilowatt costs $500.
