A new highway is to be constructed. Design A calls for a concrete pavement costing $90 per foot with a
12-year life; two paved ditches costing $4 per foot each; and two box culverts every mile, each costing
$7,000 and having a 12-year life. Annual maintenance will cost $1,700 per mile; the culverts must be
cleaned every three years at a cost of $550 each per mile.
Design B calls for a bituminous pavement costing $40 per foot with a 6-year life; three sodded ditches
costing $1.50 per foot each; and three pipe culverts every mile, each costing $2,100 and having a 6-year
life. The replacement culverts will cost $2,350 each. Annual maintenance will cost $2,600 per mile; the
culverts must be cleaned yearly at a cost of $230 each per mile; and the annual ditch maintenance will
cost $1.30 per foot per ditch.
Compare the two designs on the basis of equivalent worth per mile for a 12-year period. Find the most
economical design on the basis of AW and PW if the MARR is 6% per year.

Find both for design A and B then decide which one is the most economical, thank you.
A new highway is to be constructed. Design A calls for a concrete pavement costing $85 per foot with a 16-year life; three paved ditches costing $4 per foot each; and four box culverts every mile, each costing $8,000 and having a
16-year life. Annual maintenance will cost $1,700 per mile; the culverts must be cleaned every four years at a cost of $400 each per mile.
Design B calls for a bituminous pavement costing $40 per foot with a 8-year I four sodded ditches costing $1.45 per foot each; and two pipe culverts every mile, each costing $2,200 and having a 8-year life. The replacement
culverts will cost $2,500 each. Annual maintenance will cost $2,600 per mile; the culverts must be cleaned yearly at a cost of $220 each per mile; and the annual ditch maintenance will cost $1.65 per foot per ditch.
Compare the two designs on the basis of equivalent worth per mile for a 16-year period. Find the most economical design on the basis of AW and PW if the MARR is 8% per year.

- Ken Allen, capital budgeting analyst for Bally Gears, Inc., has been asked to evaluate a proposal. The manager of the automotive division believes that replacing therobotics used on the heavy truck gear line will produce total benefits of $516,000 (in today's dollars) over the next 5 years. The existing robotics would produce benefits of $387,000 (also in today's dollars) over that same timeperiod. An initial cash investment of $206,400 would be required to install the new equipment. The manager estimates that the existing robotics can be sold for $72,000. Show how Ken will apply marginal cost-benefit analysistechniques to determine the following:a. The marginal benefits of the proposed new robotics.b. The marginal cost of the proposed new roboticsc.
