Given $$a $$batch $$process $$with $$two $$steps$.$The $$first $$step $$requires $$a $$setup $$time $$of $$

$15$ minutes $$before $$a $$batch $$of $$items $$can $$be $$processed$,$whereas $$the $$second $$step $$does $$not $$require $$any $$setup $$time$.$The $$processing $$time $$per $$item $$at $$the $$first $$step $$is $2$

$$minutes$,$and $$that $$at $$the $$second $$step $$is $3$minutes$.$Suppose $$that $$we $$can $$use $$any $$batch $$size$,$what $$is $$the $$maximum $$possible $$process $$capacity $$per $$hour$?$Pick $$the $$best $$answer: $$
