A large household air conditioner may consume 15.0 kW of power. What is the cost of operating this air conditioner 3.00 h per day for 30.0 d if the cost of electricity is $0.110 per kW ? h ?
Added by Melissa M.
Step 1
To do this, we multiply the power consumption (15.0 kW) by the number of hours the air conditioner is operated per day (3.00 h) and the number of days (30.0 d): Total energy consumed = 15.0 kW * 3.00 h/day * 30.0 d = 1350 kWh Show more…
