    Answer: current = 10.25A

    Explanation:

    Toward = 240w

    Alarm clock = 30w

    Tanning bed = 720w

    4 60 watts bulb = 60 * 4 = 240w

    Total power = 240 + 30 + 720 + 240 = 1230w

    Voltage = 120v

    Recall that Power = current * voltage

    1230 = current * 120

    current = 1230/120 = 10.25A
