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.
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:
[tex]=2*30=60[/tex]
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:
[tex]=(1/5)*60=12[/tex]
Mr. Smith will need to appoint 12 supervisors for 60 hall monitors.
