    69.62

    Explanation:

    The calculation of this question is as below:-

    Consumption: 187W

    Everyday operates: 17hours

    cost of electricity: 0.06 per kWh

    so, the annual operating cost

    = Consumption : kWh * Everyday operates * cost of electricity * total number of days in a year

    Annual operating cost = 187W : 1000 * 17h * 0.06 * 365 days

    = 69.62
