In a particular city, electrical energy costs $0.13 per kilowatt-hour( Round your answers, in dollars. to at least two decimal places.) a. How much does it cost to operate an old-style incandescent 40.0-W light bulb continously for 24 hours? b. A modern LED light bulb that emits as much visible light as a 40.0-W incandescent only draws 4.50 W of power. How much does it cost to operate this bulb for 24 hours? c. A particular electric oven requires a potential difference of 220 V and draws of 22.0 A of current when operating. How much does it cost to operate the oven for 4.30 hours?
