If electricity costs $0.12 per kWh, then what is the total cost for a family of four to illuminate ten 60 watt bulbs each for 30 days? (Round to the nearest dollar)

$52

Explanation:

The following were obtained from the question:

Power for ten 60watts = 10 x 60 = 600watt = 600/1000 = 0.6Kw

Time = 30days = 30 x 24 = 720hrs

Energy consumed =?

Energy consumed = power x time

Energy consumed = 0.6 x 720 = 432Kwh

The cost of operating 1kwh = $0.12

Therefore, the cost of operating 432Kwh = 432 x 0.12 = $52

well off of my head we know that the perfume bottle is most likely opened, or broken. i can also tell it is moving at low and high concentration because it is covering the other side of the room. what we can obtain from this information is it explains why the odor can be detected at the other side of the room.
