A100 watt incandescent light bulb is operated for 12 hours, and a 15 watt fluorescent light bulb is operated for the same period of time. at 10 cents per kwh, what is the cost savings of the fluorescent bulb? (1 point) group of answer choices $ 1.02 $ 0.10 $ 0.01

It will be $0.138

Explanation:

We have given that a 100 watt is light bulb is operated for 12 hour

So power P = 100 watt

And time t = 12 hour

We know that energy = power × time

So energy of first bulb

And second bulb is of 15 watt and operated for same 12 hours

So energy of second ball

Total energy = 1.2+0.18 = 1.38 kWh

It is given that it will cost 10 cent per kWh

So total cost = 1.38×10 = 13.8 cents

We know that $1 = 100 cents

So 13.8 cents = $0.138

answer; wage income;
