I need someone very good in Engineering mathematicsA new highway is to be constructed. Design A calls for a concrete pavement costing $7575per foot with a 1212 -yearlife; twotwopaved ditches costing $44per foot each; and threethreebox culverts every mile, each costing $7 comma 0007,000and having a 1212 -yearlife. Annual maintenance will cost $1 comma 7001,700per mile; the culverts must be cleaned every threethreeyears at a cost of $300300each per mile.Design B calls for a bituminous pavement costing $4040per foot with a 66 -yearlife; twotwosodded ditches costing $1.551.55per foot each; and twotwopipe culverts every mile, each costing $2 comma 1502,150and having a 66 -yearlife. The replacement culverts will cost $2 comma 3502,350each. Annual maintenance will cost $2 comma 7002,700per mile; the culverts must be cleaned yearly at a cost of $235235each per mile; and the annual ditch maintenance will cost $1.701.70per foot per ditch.Compare the two designs on the basis of equivalent worth per mile for a 1212 -yearperiod.
