A new highway is to be constructed. Design A calls for a concrete pavement costing ​\$7575 per foot with a 1212​-year ​life; twotwo paved ditches costing ​\$44 per foot​ each; and threethree box culverts every​ mile, each costing ​\$7 comma 0007,000 and having a 1212​-year life. Annual maintenance will cost ​\$1 comma 7001,700 per​ mile; the culverts must be cleaned every threethree years at a cost of ​\$300300 each per mile.

Design B calls for a bituminous pavement costing ​\$4040 per foot with a 66​-year ​life; twotwo sodded ditches costing ​\$1.551.55 per foot​ each; and twotwo pipe culverts every​ mile, each costing ​\$2 comma 1502,150 and having a 66​-year life. The replacement culverts will cost ​\$2 comma 3502,350 each. Annual maintenance will cost ​\$2 comma 7002,700 per​ mile; the culverts must be cleaned yearly at a cost of ​\$235235 each per​ mile; and the annual ditch maintenance will cost ​\$1.701.70 per foot per ditch.

Compare the two designs on the basis of equivalent worth per mile for a 1212​-year period. Find the most economical design on the basis of AW and PW if the MARR is 1010​% per year.
