Installing an automated production system costing $$300,000$ is initially expected to save Zia

Corportation $$52,000$ in expenses annually. If the system needs $$7,500$ in operating and maintenance

costs each year and has a salvage value of $$30,000$ at Year $10,$ what is the IRR of this system. If the

company wants to earn $12\%$ on all investments, should this system be purchased?
