Lee watches TV for 3 hours per day. During that time, the TV consumes 150 watts per hour. Electricity costs (10 cents)/(1 kilowa

miss Akunina [59]

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
