Question
The Electric Sheep Division of Block C Enterprises has decided to investigate the potential rearrangement of one of its facilities. The first step is to evaluate the current arrangement. The tables below show the distance between the 7 departments and the number of trips necessary in a typical month. Assume that the number of reverse trips is the same (i.e., the matrices are symmetric). The average cost per trip-foot is $0.16. Calculate the TOTAL monthly costs, in dollars, of moving loads FROM department 1.

Explanation / Answer
Total cost from department 1 to all departments = (number of trips to each department)*(distance to each department)*0.16
Department 1 to 2 = 300*120 = 36000 feet
Department 1 to 3 = 50*120 = 6000 feet
Department 1 to 4 = 75*225 = 16875
Department 1 to 5 = 250*225 = 56250
Department 1 to 6 = 100*325 = 32500
Department 1 to 7 = 125*325 = 40625
Total distance covered = 36000+6000+16875+56250+32500+40625
= 188250 feet
Total cost from department 1 = 188250*0.16 = $30120
Option C = 30120
