Problem: When trying to determine between two seperate projects I understand that the EAM is the best tool. However I am not sure how to apply this.
I need to know in a step by step format how to calculate this and further how to use.
For example:
short-lived light bulbs last 2 years, cost is $5 and use of electricity is $5 annually
long-lived light bulbs last 5 years, cost is $10 and use $3 electricity annually
What would the true cost be if the discount rate = 10%?
