Ray's Satellite Emporium wishes to determine the best order size for its best$-$selling satellite dish $($model TS$111).$ Ray has estimated the annual demand for this model at $1,050$ units. His cost to carry one unit is $$105$ per year per unit, and he has estimated that each order costs $$25$ to place.

Using the EOQ model, how many should Ray order each time? $($Round your answer to the nearest whole number.$)$
