Out of school for 35 years and never taking algebra makes my kids homework a real challange, especially when my daughter is in honors math and looks to me for help. She works very hard to stay in class and I guess I have to keep up whith the times so I can be there for her and my son right behind her in school. After beating my head against the wall all week on this one problem I came acrossed this forum with a question. I can figure the answer the hard way but I am very curious about the formula. Question seems so simple:

The class made $1220.00 on a school play they sold 295 tickets, adult tickets were $5 and children were $2 how many Adult tickets were sold.

Thank You

Jim
