Question 50944
<pre><font size = 5><b>The students found that 0.016 of the teachers were either 
completely brave or fearless. If 480 teachers fell into one 
of these categories,how many teachers were there in all?

Let N = the number of teacher there were in all.

480 teachers fell into one of these categories, so

480 teachers were either completely brave or fearless

0.016 of the teachers were either completely brave or fearless.

Therefore,

480 teachers = 0.016 of the teachers

         480 = 0.016N

Divide both sides by 0.016

       30000 = N

There are 30000 teachers
