Answer:
The amount invested in CDs is $1,340
The amount invested in the stock portafolio is $6,900
The amount invested in the saving accounts is $2,300
Step-by-step explanation:
Let
x ---->the amount invested in CDs at 2.1%
y ---> the amount invested in the stock portfolio at 2.5%
z ---> the amount invested in the savings account at 1.5%
----> equation A

The total interest earned by the three amount must be equal to $231.69
so
----> equation D
substitute equation B and equation C in equation D
solve for y
<em>Find the value of x</em>
<em>Find the value of z</em>
