Answered by GPT 3.5
To calculate the cost of lighting the 500-watt outdoor light for 8 hours, we need to convert the watts to kilowatts and then multiply it by the electricity cost per kilowatt-hour.

Step 1: Convert watts to kilowatts
500 watts = 500/1000 = 0.5 kilowatts

Step 2: Calculate the total energy consumption
Energy consumption = power x time
Energy consumption = 0.5 kW x 8 hours = 4 kilowatt-hours

Step 3: Calculate the cost of lighting
Cost of lighting = energy consumption x electricity cost
Cost of lighting = 4 kWh x $0.075/kWh = $0.30

Therefore, the cost of lighting the 500-watt outdoor light for 8 hours is $0.30.
