Electrical services costs $7 per month plus $0.10 per kilowatt-hour of electricity used. (Assume that a partial kilowatt-hour is not rounded up.) a. If the resident of an apartment uses 700 kilowatts-hours in 1 month, what is the charge? b. Write an equation in slope-intercept form that gives the cost C of using x kilowatt-hours in 1 month c If the monthly electrical bill for the apartment’s resident is $57, how many kilowatt-hours were used? 4. Find a point slope form for the line that satisfies the stated conditions. Use the first point in the point-slope form.
