he Fresh Connection is looking at the needs for a new processing operation. The demand at this operation is $315$ units per day. Given the combination of regular time, overtime and some additional time available due to cross training, this operation is up and running for $18\mathrm{.}2$ hours per day across multiple shifts.

Task Time Req. $($min$.)$ Predecessor Tasks

a $10\mathrm{.}73-$

b $6\mathrm{.}83$ a

c $9\mathrm{.}25$ b

d $12\mathrm{.}17$ c

e $14\mathrm{.}08$ d

f $5\mathrm{.}82$ e

g $7\mathrm{.}99$ f

h $13\mathrm{.}63$ g

Assuming that each task must be completed in sequence and that each task has its own workstation, what is the efficiency of the line $($stated as a percent$)?$
