Question $21(1$ point$)$

A three station work cell is illustrated in the image above. A unit needs to be processed at either Machine A or Machine B for Station $1($parallel lines, both lines doing the exact same thing$).$ The unit is then processed at Stations $2$ and $3$ before leaving the work cell. The process time of each machine$/$station is indicated in the flowchart. What is the process time of this system measured in minutes$/$unit$?$

Note:

$1-$ Do not include the unit of measure in the answer. For instance, if the answer is $4\mathrm{.}6\backslash (\backslash$mathrm$\{$min$\}/\backslash$mathrm$\{$unit$\}\backslash )$ only enter $4\mathrm{.}6.$
