The Street Divislon of Labrosse Logistics Just started operatlons. It purchased depreclable assets costing $$41\mathrm{.}5mllll$ lon and having a four$-$year expected llfe, after which the assets can be salvaged for $$8\mathrm{.}3$milllon. In addition, the division has $$41\mathrm{.}5$milli on In assets that are not depreclable. After four years, the dlvislon will have $$41\mathrm{.}5$ million avallable from these non depreclable assets. Thls means that computing ROI, thls dlvislon uses end$-$of$-$year asset values in the denominator. Depreclation is computed on a stralght$-$llne basls, recognizing the salvage values noted. Ignore taxes.
