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 $70 per foot with a 16-year life; three paved ditches costing $5 per foot each; and three box culverts every mile, each costing $9,000 and having a 16-year life. Annual maintenance will cost $1,600 per mile; the culverts must be cleaned everyfour years at a cost of $450 each per mile.Design B calls for a bituminous pavement costing $55 per foot with a 8-year life; three sodded ditches costing $1.55 per foot each; and three pipe culverts every mile, each costing $2,300 and having a 8-year life. The replacement culverts will cost $2,350 each. Annual maintenance will cost $2,600 per mile; the culverts mustbe cleaned yearly at a cost of $225 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 16-year period.

A company estimates it will sell 5000 products in a year. I twould like to make some number N of equally spaced orders of size x units per order so that the total inventory cost (which includes prdering and storage) is minimized. a) If there is a 420 per order fixed cost plus a cost of $9 per unit ordered, and the storage cost per year is $10, find the number of orders and the numbers of units per order so that the goal of minimizing inventory costs is achieved. b) Suppose that the ordering cost doubles to $18 per unit ordered,and that no other chnage is made.
