Problem- For similar light intensity, compact flourescent bulbs use about 25% of the energy of incandesant bulbs. Lets say you replaced a bulb of 75 W with a flourescent bulb and that your utility charges $0.15/kW-hour. How many dollars would you save in electricity in the 10,000-hour lifetime of the bulb?

Please show me how work it out above problem
