if your power company charges about 10 cents per kilowatt-hour, how much would your energy cost per day if you bought it from the power company?
The Correct Answer and Explanation is :
To calculate your daily energy cost, you first need to know how much electricity you are using in kilowatt-hours (kWh) each day. Let’s assume you use a certain number of kWh per day—here, I will go through the steps using an example:
Step-by-Step Calculation:
- Find your total kWh usage per day: This depends on how much energy your appliances or devices use. For instance, if you use 30 kWh in a day, that’s the amount of electricity you’re consuming.
- Cost per kWh: If your energy company charges 10 cents per kWh, this is the rate you will pay for each kilowatt-hour of energy you use.
- Multiply the kWh by the cost per kWh:
[
\text{Daily Energy Cost} = \text{Energy Usage (kWh)} \times \text{Cost per kWh}
]
[
\text{Daily Energy Cost} = 30 \, \text{kWh} \times 0.10 \, \text{\$}
]
[
\text{Daily Energy Cost} = 3.00 \, \text{\$}
]
In this example, if you used 30 kWh in a day, your daily cost would be $3.00.
Explanation:
Electricity bills are typically calculated based on your energy consumption, which is measured in kilowatt-hours. One kilowatt-hour is the amount of energy used by a 1,000-watt appliance running for one hour. Power companies set a price per kWh, which you pay based on how much you use. In this example, 10 cents per kWh is the charge, and this rate determines how much you pay for each unit of electricity.
Your daily energy cost will vary depending on your total energy consumption. If you use more electricity, your bill will increase proportionally, and if you use less, it will decrease. Understanding this calculation can help you manage and reduce your energy costs by being mindful of how much power you use in your daily activities.
