lee watches tv for 4 hours oer say during thst time the tv consumes 150 watts per hour electricty cots 18 cents 1kilowatt hour. how much cents does lees tv cost to operare for a month of 30 days

To find out how much it costs for Lee to operate his TV for a month, we'll break down the problem step by step.

1. **Determine the daily energy consumption in kilowatt-hours (kWh):**
   - The TV consumes 150 watts per hour.
   - Lee watches TV for 4 hours per day.
   - Energy consumption per day = \( 150 \text{ watts} \times 4 \text{ hours} \)
   - Convert watts to kilowatts: \( 150 \text{ watts} = 0.15 \text{ kW} \)
   - Energy consumption per day = \( 0.15 \text{ kW} \times 4 \text{ hours} = 0.6 \text{ kWh} \)

2. **Calculate the monthly energy consumption:**
   - There are 30 days in the month.
   - Monthly energy consumption = \( 0.6 \text{ kWh/day} \times 30 \text{ days} = 18 \text{ kWh} \)

3. **Determine the cost per kilowatt-hour:**
   - The cost of electricity is 18 cents per kWh.

4. **Calculate the total cost for the month:**
   - Total cost = \( 18 \text{ kWh} \times 18 \text{ cents/kWh} = 324 \text{ cents} \)

So, Lee's TV costs **324 cents** to operate for a month of 30 days.

Would you like more details or have any questions? 

Here are 5 related questions to expand on this problem:
1. How would the cost change if Lee watched TV for 5 hours per day instead?
2. What would be the monthly cost if the electricity rate increased to 20 cents per kilowatt-hour?
3. How much energy in kilowatt-hours does Lee's TV consume in a year?
4. How does the energy consumption of Lee's TV compare to a more energy-efficient model that uses 100 watts per hour?
5. If Lee reduces his TV watching by 1 hour per day, how much would he save in electricity costs per month?

**Tip:** To reduce electricity costs, consider using energy-efficient appliances and limiting usage when possible.
