4. 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. Neglect the element of availability. (20 points) (a) Determine the breakeven quantity
