A small welding business owner is considering a new contract. The project requires purchasing a new welding truck for $$73,000$ with a residual value of $45\%$ of its original value after eight years. It is estimated to yield annual net returns of $$18,000$ for six years starting in three years. Should the project be undertaken, if the small business owner would like to secure a $3\%$ yield rate? $(4$ marks$)$
