<PRE><B>Question 943164</B>
A=number Adults, C=number children B=admission bill
$14A+$11C=B ANSWER A:General equation 
 Solve for C: subtract $14A from each side
{{{$14A+$11C-$14A=B-$14A}}}
{{{$11C=B-$14A}}} divide each side by $11
{{{$11C/($11)=(B-$14A)/($11)}}}
{{{C=(B-$14A)/$11}}}
Substitute given values: with 9 adults (A) and Bill(B)=$896
{{{C=($896-$14(9))/$11}}}
{{{C=($896-$126)/$11}}}
{{{C=$770/$11}}}
{{{C=70}}} ANSWER 70 children went on the field trip</PRE>
