Alight bulb consumes 18900 watt-hours in 5 days and 6 hours. how many watt-hours does it consume per day?

The answer is 3,600.

There's 24 hours in a day and therefore 120 in 5, add 6 gives you 126.

18900/126=150

So 150 kWh used every hour,

150x24= 3600.

So 3600 kWh used every day.

Hope this helps :)

Multiply 9 and 67. then multiply 3 with 67. lastly the answer that you got for 9x67 is to be subtracted by the answer you got for 3x67
