Question 1191881
x=stocks and income is 0.084x
bonds and CDs together are $85000-x. Let CDs be y and bonds y+25000
y+25000+y=85000-x
2y=60000-x
y=30000-0.5x
CDs are 30000-0.5x and income is (30000-0.5x)(0.0525)=1575-0.02625x
bonds are 55000-0.5x and income is (55000-0.5x)(0.021)=1155-0.0105x

add those three terms to get $4147.5-0.04725x=$2730
-0.04725x=-1417.5
x=$30000
so $30000 in stocks for income of $2520
$15000 in CDs for income of $787.50
$40000 in bonds for income of $840
