Question 838262
If you add up the percentages, 
{{{ 5 + 5 + 10 + 35 + 45 = 100 }}} percent
That means the entire 6th grade is
accounted for
-----------------
The {{{30}}} 6th graders who own birds are 5%
of the whole class
------------------
Let {{{ c }}} = the number of 6th graders
{{{ .05c = 30 }}}
{{{ c = 30/.05 }}}
{{{ c = 600 }}}
600 were surveyed
