Solve step by step clearly and type otherwise I'll dislike Guardian is a national manufacturing company of home health care appliances. It is faced with a make-or-buy decision. A newly engineered lift can be installed in a car trunk to raise and lower a wheelchair. The steel arm of the lift can be purchased internationally for $3.50 per unit or made in-house. If manufactured on site, two machines will be required. Machine A is esti- mated to cost $18,000, have a life of 6 years, and have a S2000 salvage value; machine B will cost $12,000, have a life of 4 years, and have a S-500 salvage value (carry-away cost). Ma- chine A will require an overhaul after 3 years costing $3000. The annual operating cost for machine A is expected to be $6000 per year and for machine B is S5000 per year. A total of four operators will be required for the two machines at a rate of $12.50 per hour per operator. In a normal 8-hour period, the operators and two machines can produce parts sufficient to manufac ture 1000 units. Use a MARR of 15% per year to determine the following. (a) Number of units to manufacture each year to justify the in-house (make) option. (b) The maximum capital expense justifiable to purchase machine A, assuming all other esti- mates for machines A and B are as stated. The company expects to produce 10,000 units per year.
