💡 Example: Estimating a Monthly Bill
Let’s say you want to estimate your upcoming electricity bill. Here’s how it might look:
- Electricity Used: 600 kWh
- Cost Per kWh: $0.15
Calculation:
600 kWh × $0.15 = $90.00
That means your estimated electricity cost for the month is $90.00.
This is especially helpful if you’re trying to stay within a budget or understand fluctuations in your energy consumption.
