Glen just turned 19 and is about to start college at DePaul. His parents started saving for his college 8 years ago, on his 11th birthday. They put $7,000 into his college account on his 11th birthday, $9,000 on his 12th birthday, and $4,000 on his 19th birthday (and today is his 19th birthday). If the money was all invested at a rate of 9%, how much is now in Glens college account?
