Problem $15-1($Algo$)$

A manager at Strateline Manufacturing must choose between two shipping alternatives: two$-$day freight and five$-$day freight. Using five$-$day freight would cost $$210$ less than using two$-$day freight. The primary consideration is holding cost, which is $$10$ per unit a year. $2,450$ items are to be shipped.

Which alternative would you recommend? $($Do not round your intermediate calculations.$).$
