Samsung Electronics is trying to reduce supply chain risk by making more responsible

make$-$buy decisions through improved cost estimation. A high$-$use component

$($expected usage is $5000$ units per year$)$ can be purchased for $$25$ per unit with delivery

promised within a week. Alternatively, Samsung can make the component in$-$house

and have it readily available at a cost of $$5$ per unit, if equipment costing $$150,000$ is

purchased. Labor and other operating costs are estimated to be $$35,000$ per year over

the study period of $5$ years. Salvage is estimated at $10\%$ of first cost and $i=12\%$ per

year. What is the breakeven quantity?
