An energy-efficient lightbulb, taking in 23.0 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 $5.00, whereas the conventional bulb has lifetime 750 h and costs $0.60 per bulb. determine the total savings obtained by using one energy-efficient bulb over its lifetime as opposed to using conventional bulbs over the same time period. assume an energy cost of $0.20 per kilowatt-hour.

This problem has been solved! see the answerwhich of the following statements is correct? the consumer price index is a measure of the overall level of prices, whereas the gdp deflator is not a measure of the overall level of prices. if, in the year 2011, the consumer price index has a value of 123.50, then the inflation rate for 2011 must be 23.50 percent. compared to the gdp deflator, the consumer price index is the more common gauge of inflation. the consumer price index and the gdp deflator reflect the goods and services bought by consumers equally well.
