$1\mathrm{.}9$ The starting work part costs $$2\mathrm{.}00$ in a batch production operation. Batch quantity $=100$ parts. Each cycle, part handling time $=0\mathrm{.}40$ min, and operation time $=1\mathrm{.}52$ min. Setup time $=50$ min. Equipment cost rate $=$ $$30\mathrm{.}00/$hr$,$ and labor cost rate $=$ $$18\mathrm{.}00/$hr$,$ including overhead costs. There is no tool change or tool cost in the operation. The machine tool is $100\%$ reliable, and scrap rate $=2\%.$ Determine $($a$)$ pro$-$ duction rate, $($b$)$ finished part cost, and $($c$)$ number of hours required to complete the batch
