The weekly total material handling cost of the layout is $74400
Explanation:
The following is used in order to calculated the given problem
Distance between the work areas is as follows:
AB=4
AC=9
AD=7
BC=7
BD=9
CD=9
Cost = 4 times 800 + 9 times 700 + 7 times 500 + 7 times 400 + 9 times 200 + 9 times 800 = 24800
As it costs $3 to move one work piece one foot, the total weekly cost = [tex]24800 \times 3[/tex] = $74400
Thus, the weekly total material handling cost of the layout is $74400
