    Answer:

    12

    Step-by-step explanation:

    Mr Smith appoints the following people:

    2 hall moniters for every hallway

    4 supervisors for every 20 hall monitors.

    There is 30 hallways

    From this information we can determine the amount of of all monitors for 30 hallways as:

    =2*30=60

    Therefore Mr Smith appoints 60 hall monitors.

    We can calculate the number of supervisors per hall monitors:

    [ted]=4/20=1/5[/tex]

    Therefore we can determine the amount of supervisors Mr. Smith needs to appoint is:

    =(1/5)*60=12

    Mr. Smith will need to appoint 12 supervisors for 60 hall monitors.

    2 monitors for each hallway, 30 hallways, this means there are 60 total monitors. There are 3 sets of 20 monitors, and 4 for each set, which means that there are 12 supervisors needed to be appointed.
