Answer:

2250 watt-hours

Step-by-step explanation:

Convert 3 days and 18 hours= 3 days + 3/4 days=3.75 days

1 day a light bulb consumes 600 watt-hours

3.75 days a light bulb consumes 600x3.75 watt-hours

Answer:

2250 watt-hours

Step-by-step explanation:

Okay, so we first need to find out how many watt-hours the light bulb consumes in 1 hours, so we need to divide 600 by 24 hours, which gives us a rate of 25 watt-hours per hour.

So if the light bulb consumes 600 hours per day, and it runs for 3 days, you multiply 600 by 3 to get 1800.

And because we know that it also consumes 25 watt-hours per hour, we multiply 25 and 18 together to get 450 hours.

Finally, you add 1800 and 450 together to get 2250 watt-hours.

Hope this helps :)
