Answer:
135 cent
Step-by-step explanation:
Given that:
Cost of electricity = 10cent / 1 kilowatt hour
TV consumption = 150watt per hour
Duration = 3 hours
Cost of operating for 30 days
Total energy usage per day: (150 watt/hr) * 3 hours = 450 watts = 450/1000 = 0.45kW
Total energy for 30 days = 0.45 * 30 = 13.5 Kilowatt
Cost per kilowatt = 10cent
13.5 kw = 13.5 * 10 cent = 135 cent
135 cent = $1.35
