A total of $11,000 was invested. Part of the $11,000 was invested at 4% and the rest invested at 7%. If the investments earn $680 per year, how much was invested at each rate?

3 answers

(x)(.04)+(11000-x)(.07)=680

where x=the amount of money invested at 4%
and 11000-x = the rest of the 11000 invested at 7%
4800
