A company is considering buying a new machine for its main factory. The new machine initial cost $($investment$)$ is $10741$ and it can work $4$ years before being scrapped. You can assume that a new one would then be bought, and that the company can renew this forever. Suppose that using the machine costs $1133$ per year $($after tax$).$ What is the equivalent annual cost of this investment if the RRR is $12,69\%$ per year?
