There are three alternatives X,Y,Z. With 10% MARR, which alternative should be chosen based on following conditions and why?  For X, initial cost is $10k, yearly revenue is $6K, Salvage is   $1k and useful life is calculated as   2yrs. For Y, initial cost is $15k, yearly revenue is $10K, Salvage is   -$2k and useful life is calculated as 3yrs. For Z, initial cost is $12k, yearly revenue is $5K, Salvage is $3k and useful life is calculated as 4yrs.

A new highway is to be constructed. Design A calls for a concrete pavement costing $80 per foot with a 20-year life; four paved ditches costing $3 per foot each; and four box culverts every mile, each costing $10,000 and having a 20-year life. Annual maintenance will cost $1,600 per mile; the culverts must be cleaned every five years at a cost of $400 each per mile. Design B calls for a bituminous pavement costing $55 per foot with a 10-year life; four sodded ditches costing $1.40 per foot each; and four pipe culverts every mile, each costing $2,100 and having a 10-year life. The replacement culverts will cost $2,450 each. Annual maintenance will cost $2,600 per mile; the culverts must be cleaned yearly at a cost of $225 each per mile; and the annual ditch maintenance will cost $1.55 per foot per ditch. Compare the two designs on the basis of equivalent worth per mile for a 20-year period. Find the most economical design on the basis of AW and PW if the MARR is 12% per year. Click the…
