Adult and children ticket equation

[lisamg9657]

I tried to figure this out through my book and still get my answers wrong. Maybe someone can help me find the correct formula with the story problem: A total of [FONT=MathJax_Main]900[/FONT] tickets were sold for a game for a total of $[FONT=MathJax_Main]1[FONT=MathJax_Main],[/FONT][FONT=MathJax_Main]775.00[/FONT][/FONT]. If adult tickets sold for $[FONT=MathJax_Main]2.50[/FONT] and children's tickets sold for $[FONT=MathJax_Main]1.50[/FONT], how many of each kind of tickets were sold? I tried to multiply the second equation by 10 to get rid of the decimals and then the top equation by -10. I still come with the same answer and its wrong. Help?

Please show your work. How can we tell where you are going wrong if we do not see what equations you used and how you manipulated them?

Maybe the answer key is wrong. What answer did you get?
