Final answer:
The energy consumption of the bulb over 4 days and 6 hours is 6120 watt-hours. This is calculated by multiplying the daily consumption (1440 watt-hours) by 4, and then adding the consumption for the extra 6 hours at the hourly rate (60 watt-hours/hour).
Step-by-step explanation:
To calculate the energy consumption of the light bulb in 4 days and 6 hours, you would first find out how many watt-hours the bulb uses in one day and then multiply that by the number of days. After that, you would add the consumption for the additional hours.
The bulb consumes 1440 watt-hours per day. Over 4 days, it would therefore consume:
1440 watt-hours/day × 4 days = 5760 watt-hours
For the additional 6 hours, we calculate the hourly rate first:
1440 watt-hours/day ÷ 24 hours/day = 60 watt-hours/hour
Then we multiply this rate by 6 hours:
60 watt-hours/hour × 6 hours = 360 watt-hours
Finally, we add the energy consumption for the 4 days and the additional 6 hours together to get the total consumption:
5760 watt-hours + 360 watt-hours = 6120 watt-hours
