will reduce his component lot sizes. He has developed the following data for one component, the safety chain clip:

$\backslash$table$[[$Setup labor cost,$$20$ per hour$],[$Annual holding cost,$$15$ per unit$],[$Daily production,$1,008$ units $\frac{?}{8}$ hour day$],[$Annual demand,$33,000(275$ 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 achleved $=$ minutes $($round your response to two decimal places$).$
