Answer:
36.50$
Step-by-step explanation:
The power of the light bulb in this problem is
P = 100 W = 0.1 kW
And the light bulb is operated for a time of
t = 10 hours
per day.
The light bulb is operated over 1 year (365 days), so the number of hours of operation is:
So the total energy consumed by the light bulb is
We know that the cost of operation is
p = 10 cents/kWh
Therefore, the total cost will be:
So, 3650 cents, or 36.50$.
