O.K. vg, I did like the way it started out.  Just thought the 3rd line would of been a+c=325.

radar · Answer

It would of went this way.
Let c = number of childrens tickets sold
Let a = number of adult tickets sold.
a+c=325   You now have one equation with two unknowns.  You are given cost information lets use that to get another equation
10.50a = amount of money made on adult tickets
7c= amount of money made on children tickets    (in dollars of course)
$10.50a + $7.00c = $2982  Now you have the second equation with two unknowns.

Here are your two equations:
a+c=325
$10.50a + $7.00c = $2982

You can use the substitution method to solve it.  Did you follow with understanding.
