The annual operating cost of the refrigerator is $102.78.
Explanation:
Power consumed by the refrigerator = 247 W = 247/1000 = 0.247 kW

Annual operation of the refrigerator = 365 × 19 = 6,935 hours
Annual energy consumed = 0.247 kW × 6,935 hours = 1712.945 kWh
1 kWh of electricity cost $0.06
1712.945 kWh will cost 1712.945 × $0.06 = $102.78
Annual operating cost = $102.78
