The AW value for Design A is ​$ /mi. ​(Round to the nearest​ hundreds.)

The PW value for Design A is ​$ /mi. ​(Round to the nearest​ hundreds.)

The AW value for Design B is $ /mi. ​(Round to the nearest​ hundreds.)

The PW value for Design B is ​$ /mi. ​(Round to the nearest​ hundreds.)

The most economical design on the basis of AW and PW is

A new highway is to be constructed. Design A calls for a concrete pavement costing $85 per foot with a 12-year life; two paved ditches costing $5 per foot each; and two box culverts every mile, each costing $8,000 and having a 12-year life. Annual maintenance will cost $1,800 per mile; the culverts must be cleaned every three years at a cost of $400 each per mile. Design B calls for a bituminous pavement costing $40 per foot with a 6-year life; two sodded ditches costing $1.55 per foot each; and two pipe culverts every mile, each costing $2,100 and having a 6-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 $1.45 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 10% per year. Click the icon to view the interest and annuity table for discrete compounding when the MARR is 10% per year.
