Laila Monroe · Answer 1

1) Consumption: 875 kWh / month

2) New rate:

- 7.5 cents / kWh for the first 600 kWh

- 13.0 cents / kWh the next 600 kWh

3) Calculation:

600 kWh * 7.5 cents / kWh + (875 kWh - 600 kWh) * 13.0 cents / kWh.

4500 cents + 3575 cents = 8075 cents = $ 80.75, which rounded to the nearest dolar is $ 81.

Answer: option d. $81.
