Question $25(1$ point$)$

Consider a manufacturing process depicted by the following flowchart.

Station A has $3$ parallel operators, A$1,$ A$2,$ and A$3.$ Station C has $2$ parallel operators,

$C1$ and $C2.$ Each unit only needs to be processed by one of the operators A$1,$ A$2$ and

A$3.$ After being processed at Station B $($with a single operator$),$ a unit then needs to

be processed by either $C1$ or $C2.$ The process time of the individual operators are

given as follows.

Each of A$1,$ A$2,$ and A$3$: $21$ minutes

B: $9$ minutes

Either of C$1$ and C$2$: $4$ minutes.

It is observed that the utilization of Station B is $44\%.$ What is the throughput rate $($in

units$/$hour$)$ of this process?

Note: Round your final answer to $2$ decimal places if it is not a whole number.
