*[tex \LARGE \ \ \ \ \ \ \ \ \ \  3000(1\,+\,r)^2\,+\,1000(1\,+\,r)\ =\ 4654.30]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \  3000(1\,+\,2r\,+\,r^2)\ +\ 1000(1\,+\,r)\ =\ 654.30]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \  3000r^2\,+\,7000r\,-\,654.30\ =\ 0]


Solve the quadratic for the positive root, then convert from a decimal to a percentage.  Round appropriately.
