one component, the safety chain clip:

$\backslash$table$[[$Setup labor cost $$25$ per hour,$],[$Annual holding cost $$15$ per unit,$],[$Daily production $1,008$ units$/8$ hour day,$],[$Annual demand,$30,000(250$ days each $$ daily demand of $120$ units$)],[$Desired lot size,$126$ units $($one hour of production$)]]$

To obtain the desired lot size, the set$-$up time that should be achieved $=$ minutes $($round your response to two decimal places$).$
