Answer:
The amount $15000 is divided as
in 2% = $7000
in 5% = $8000
Step-by-step explanation:
It is given that the total amount is $15000 and rates of interests are 2% and 5%.
<em>Let the amount invested in 2% be "x", so the amount invested in 5% is (15000 - x).</em>
The annual interest on x part is given as,
= 
Similarly, The annual interest on (15000 - x) part is given as,
= 
the total annual interest is given as $540
Thus, <em>540 =
</em>
<em>54000 =
</em>
<em>21000 = 3(x)</em>
x =
= 7000
Thus the shares are $7000 and (15000 - 7000) $8000 .
