Face masks made of coconut oil cost $$4\mathrm{.}00$ per unit and are retailed at a price of $$10\mathrm{.}00$ each. The cost of holding inventory is $25\%$ of the item's cost, and placing an order costs $$30\mathrm{.}00.$ If the annual demand for these masks is $96,000$ units, what would be the economic order quantity to minimize costs?
