The o'neill shoe manufacturing company will produce a special-style shoe if the order size is large enough to provide a reasonable profit. for each special-style order, the company incurs a fixed cost of $2000 for the production setup. the variable cost is $60 per pair, and each pair sells for $80.let x indicate the number of pairs of shoes produced. develop a mathematical model for the total cost of producing x pairs of shoes. tc =let p indicate the total profit. develop a mathematical model for the total profit realized from an order for x pairs of shoes. p =how large must the shoe order be before o'neill will break even? x =
