$"$An automaker is considering installing an advanced design display system at a cost of $$304,000($including hardware and software$).$ With the advanced modeling system, designers will have the ability to view their design from many angles and to fully account for the space required for the engine and passengers. The digital information used to create the computer model can be revised in consultation with engineers, and the data can be used to run milling machines that make physical models quickly and precisely. The automaker expects to decrease the turnaround time for designing a new automobile model $($from configuration to final design$)$ by $20\%.$ The expected savings in dollars is $$162,000$ per year. The training and operations and maintenance cost for the new system is expected to be $$64,000$ per year. The system has a five$-$year useful life and can be depreciated according to the five$-$year MACRS class. The system will have an estimated salvage value of $$6,500.$ The automaker's marginal tax rate is $21\%.$ Compute the rate of return of the project. Enter your answer as a percentage rounded to the nearest tenth of a percent $($i$.$e$.,8\mathrm{.}3\%$ should be entered as $8\mathrm{.}3)."$
