Answer:

  • $25.92

Step-by-step explanation:

  • 1 bulb in 1 hour = 0.06 kWh
  • Unit of cost = 12 cents per kWh = $0.12 per kWh

5 bulbs in 30-day month will consume electricity:

  • 5*0.06*30*24 = 216 kWh

The total cost is:

  • 216 * 0.12 = $25.92

Total electricity consumed per day

  • 24(0.06)
  • 1.44Kwh

Consumed in 30days

  • 30(1.44)
  • 43.2Kwh

For 5bulbs

  • 5(43.2)
  • 216kwH

Cost

  • 216(0.12)
  • $25.92
