    Satellite, did you set that up as two equations then substitute y into the first one?

    .07x + .09y = 1590 x + y = 19000

    Hero the right answer is not D_= 6000 in bonds, is it?

    no i reasoned as follows. put x = amount in 7% CD, then since the total is 19000 the rest must be 19000 - x

    But the equation comes out in the same manner as what you posted

    yes of course. i put x = amount in 7% and got x = 6000 so that is the amount in municipal bonds. the rest is in the 9% stuff

    i guess i just did the y = 19000 - x part in my head

    I'm thinking x is the amount invested in bonds and y is the amount invested in certificates, right?
