Your company evaluates proposals using a 2.5-year payback period. You have two alternatives for a new boring machine. Alt. A costs $10,000 and will last for six years. Alt.A will save $5,000 in year one and $2,000 in year two. Alt. B will cost $15,000 and will last for six years. Alt.B will save $7,000 in year one and $1,000 in year two. Assume a MARR of 12%. (a) What savings in year 3 is needed to make Alt. A an acceptable project? (b) What savings in year 3 is needed to make B an acceptable project? (c) If you believe that the year 3 savings will be $7,000 for A and $9,000 for B, which will you buy?
