What is the total cost (including the price of the bulbs) to run incandescent buibs for 3.0 years? constants compact fluorescent buibs are much more efficient at producing light than are ordinary incandescent bulbs. they initially cost much more, but last far longer and use much less electricity. according to one study of these bulbs, a compact bulb that produces as much light as a 100 w incandescent bulb uses only 23.0 w of power. the compact bulb lasts 1.00x10 hours, on the average, and costs $ 11.0 whereas the incandescent bulb costs only 76.0 g, but lasts just 750 hours. the study assumed that electricity cost 8.00 ¢ per kwh and that the buibs were on for 4.0 h per day. vπ ασφ 31 ? 805.92 dollars) submit previous answers request answen xincorrect; try again; 5 attempts remaining part b what is the total cost (including the price of the bulbs) to run compact fluorescent bubs for 3.0 years? aedb 7 dollar(s)
