Calculate A CFL produces approximately four times more light output per watt than
incandescent lamps do. This means that a 100-W incandescent lamp can be replaced
with 25-W CFL. If you replaced 15 100-W bulbs with 25-W CFLs, how many fewer watts
of power will you use? If your electric bill for the incandescent lights was $20 in a month
and you use the CFLs for the same number of hours, what would the new bill be?
