A TES (Thermal Energy Storage) system is installed that will cost $89,000 and is projected to save $35,684 annually for the life of the project of 18 years. What is the exact Internal Rate of Return (IRR)

the exact internal rate of return is 40%

Explanation:

The computation of the exact internal rate of return is shown below

Given that

Initial investment = -$89,000

Year 1 to Year 18 = $35,684 each year

Based on the above information

We use the IRR formula

= IRR()

After applying the internal rate of return formula, the exact internal rate of return is 40%

So the same is considered and relevant too

metallurgy is your answer

the "study of metals and the process of refining ("

note that it says metal. metallurgy has the word "metal" in it, and so is most likely your answer (and is your answer).
