I need someone very good in Engineering mathematics
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.
