Algebra help, Income earned on an IRA investment help?

I need some help on setting up this problem, and how to find the formula to get the correct answer.. this sounds like a different language like where do I start? Can I put this in a table or a chart to get the equations?

Here it is: A student receives a yearly income of $4,900 from a$70,000  account set up by her grandparents to help fund his education. From this educational account $20,000 is invested in a secure Treasury bond earning 4.5% yearly interest. What rate of return must he earn on the rest of this investment to produce the yearly income of$4,900?
