Answer

0.16 toea/day\text{0.16 toea/day}

Step-by-step solution

3 steps

  1. Convert the power from watts to kilowatts.

    P=25 W=251000 kW=0.025 kWP = 25 \text{ W} = \frac{25}{1000} \text{ kW} = 0.025 \text{ kW}

  2. Calculate the energy consumed per day in kilowatt-hours (KWh).

    E=P×tE = P \times t E=0.025 kW×10 hrs/dayE = 0.025 \text{ kW} \times 10 \text{ hrs/day} E=0.25 KWh/dayE = 0.25 \text{ KWh/day}

  3. Calculate the cost of power used per day.

    Cost=E×Rate\text{Cost} = E \times \text{Rate} Cost=0.25 KWh/day×0.64 toea/KWh\text{Cost} = 0.25 \text{ KWh/day} \times 0.64 \text{ toea/KWh} Cost=0.16 toea/day\text{Cost} = 0.16 \text{ toea/day}

    The cost of power used by the DVD player is 0.16 toea/day.

    0.16 toea/day\text{0.16 toea/day}
