Cori's Dog House is considering the installation of a new computerized pressure cooker for hot dogs. The cooker will increase

sales by $$9,500$ per year and will cut annual operating costs by $$11,450.$ The new system will also prompt a $$5,200$ increase in

net working capital. The system will cost $$59,000$ to purchase and install. This system is expected to have a $4-$year life and will

be depreciated to zero using straight$-$line depreciation and have no salvage value. The tax rate is $21$ percent and the required

return is $10\mathrm{.}2$ percent. What is the NPV of purchasing the pressure cooker?
