Answer:
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
