Note: This is. computationally, the longest problem. You might want to consider answering the rest and coming back to this one. Or at least do not spend more than 15 minutes on it before moving on to the rest and coming back if there is time.   A small business is considering purchasing a commercial 3D printer. The equipment costs $1,200 today and is expected to generate $`A`per year in savings for the next 5 years. There is no salvage value. Determine the Internal Rate of Return (IRR) for this investment.
