Question 650754
Amount invested in bonds and cd = $75,000
Let the amount invested in bonds= $x
and amount invested in cds= $y
According to the question, $x= $y+$4,000    ...(1)
 $x +$y= $75,000                            ...(2)
Now substitute the value of x in equation 2
 $y+ $4,000 + $y= $75,000
 $2y + $4,000= $75,000
 $2y = $75,000- $4,000
 $2y = $71,000
 $y= $71,000/2
  y= $35,500-------Amount invested in cds
  x= 35,500 +4,000
  x= $39,500-------Amount invested in bonds
