Maricopa Success invested $ 73500 in bonds.
Maricopa Success invested $ 33000 in CDs.
Answer by Boreal(15235)   (Show Source):
You can put this solution on YOUR website! x=bonds
stocks+CDs=170000-x
but x-10000=CDs
therefore, stocks+(x-10000)=170000-x
stocks=180000-2x
0.022x+0.0325(x-10000)+0.073(180000-2x)=170000
0.022x-325+0.0325x+13140-0.146x=7325
-0.0915x=-5490
x=$60,000 in bonds earn 1320
x-10000=$50,000 in CDs, earn 1625
180000-2x=$60,000 in stocks earn 4380. They add to $7325.
