Two different liquid filter systems are being studied to clarify a liquid stream. A traditional filter will operate for one $8-$hour shift before being replaced. A special pleated design can last one full week, operating $24$ hours a day $(3$ shifts$),5$ days per week. Labor cost to change a filter is estimated to be worth $$10\mathrm{.}00$ for each filter change because a mechanic would work overtime to change the filter. The traditional filters cost $$3\mathrm{.}50$; the special pleated filters cost $$90\mathrm{.}00.$ Which filter should be chosen?
