Homework #1 
Bus Adm 476 Lec 203 Logistics and Transportation Management 
Problem 1. (Chapter 1: Business Logistics/Supply Chain-A Vital Subject) Suppose that a 
manufacturer of men’s shirts can produce a dress shirt in its Huston, Texas plant for $8 per shirt 
(including the cost of raw materials). Chicago is a major market for 100,000 shirts per year. 
Transportation and storage charges from Huston to Chicago amount to $5 per hundredweight 
(cwt.) Each packaged shirt weighs 1 pound. 
As an a...
