Question 1104048: My problem is:
LED replacement lightbulbs in a park will save the park district $374.69 per year in electricity costs. Additionally, LED bulbs last much longer than traditional bulbs, which need to be replaced every 1.4 years at a total cost of $120. How long will it take for the cost savings to recoup an initial $6,000 investment if the LED bulbs don't have to be replaced during that time?
I simply cannot remember how to set this problem up. It feels like a limit equation but I know that isn't it.
