An LED lightbulb, taking in 30 W of power, can produce the same level of brightness as a conventional lightbulb operating at power 100 W. The lifetime of the energy-efficient bulb is 10,000 h and its purchase price is $4.00, whereas the conventional bulb has lifetime 750 h and costs $0.708 per bulb. Determine the total savings (in dollars) obtained by using one energy-efficient bulb over its lifetime as opposed to using conventional bulbs over the same time period. The...

Compact fluorescent bulbs 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 10000 hours, on the average, and costs $ 11.00, whereas the incandescent bulb costs only $ 0.76, but lasts just...
