the following information: • It is equivalent to a 75 Watt incandescent lightbulb. • It uses 20 Watts of electricity. • It is estimated to last 25,000 hours. The purchase price of the lightbulb is $51.99. • The package claims an estimated energy cost of $2.41 per year, but this estimate is not based on local electricity costs. Assume that local electricity costs $0.086 per kW-hr. Based on this information, we can now calculate the cost of ownership for this bulb. The cost of ownership is defined as the purchase price of the lightbulb plus the cost of the electricity required to run the lightbulb until failure. Note the equation below: Purchase price + Total electricity cost = %3D Cost of ownership Calculate the cost of ownership for this lightbulb.

You have a Switch LED Lightbulb with
the following information:
• It is equivalent to a 75 Watt
incandescent lightbulb.
• It uses 20 Watts of electricity.
• It is estimated to last 25,000 hours.
The purchase price of the lightbulb is
$51.99.
• The package claims an estimated
energy cost of $2.41 per year, but
this estimate is not based on local
electricity costs.
Assume that local electricity costs
$0.086 per kW-hr.
Based on this information, we can now
calculate the cost of ownership for this
bulb. The cost of ownership is defined as
the purchase price of the lightbulb plus
the cost of the electricity required to run
the lightbulb until failure. Note the
equation below:
Purchase price + Total electricity cost =
Cost of ownership
Calculate the cost of ownership for this
lightbulb.
