Final answer:
Amy's total electricity bill for the month is $100, which includes the cost of 250 kWh at $0.30 per kWh and a $25 maintenance fee.
Step-by-step explanation:
To calculate Amy's electricity bill for the month, we need to consider both her usage in kilowatt-hours (kWh) and the fixed maintenance fee. Amy used 250 kWh of electricity at a rate of $0.30 per kWh, plus a $25 maintenance fee. First, we'll calculate the cost of her electricity usage:
- Electricity usage cost = Electricity rate per kWh × Total kWh used
- Electricity usage cost = $0.30 × 250 kWh
- Electricity usage cost = $75
Now we'll add the maintenance fee to find the total bill:
- Total electricity bill = Electricity usage cost + Maintenance fee
- Total electricity bill = $75 + $25
- Total electricity bill = $100
Therefore, Amy's total electricity bill for the month is $100.
