Jorge purchased municipal bonds yielding 6% annually and certificates of deposit yielding 8% annually. If Jorge's investments total $9000 and his annual income is invested in bonds and how much is invested in certificates of deposit? How would I set up an equation and solve the problem? Thanks

If the amount invested in bonds is B dollars, (9000  B) dollars is invested in certificates of deposit. If the question means that the generated annual income equals the amount initially invested in bonds (which isn't clear from the ungrammatical wording), you can form the equation B = (6/100)B + (8/100)*(9000  B), which has solution B = 12000/17, so that the amount invested in certificates of deposit is 141000/17 dollars.
