$1.$ Relative to the U$.$S$.$ distribution network, calculate the cost associated with running the existing system. Assume that $40$ percent of the volume arrives in Seattle and $60$ percent in Los Angeles and that the port processing fee for federal processing at both locations is $$5\mathrm{.}00$ per CBM$.$ Assume that everything is transferred to the Kansas City distribution center by rail, where it is unloaded and quality$-$checked. Assume that all volume is then transferred by truck to the nine existing warehouses in the United States.
