Paul has $30,000 to invest. His intent is to earn 15% interest on his investment. He can invest part of his money at 8% interest

Answer:

Amount invested at 8% is $9000 and amount invested at 18% is $21000.

Step-by-step explanation:

Let amount invested at 8% be x.

Let amount invested at 18% be y.

We get the 1st equation as:

$x+y=30000$ ........(1)

We get the second equation as:

$0.08x+0.18(y)=0.15\times30000$

=> $0.08x+0.18y=4500$

or getting rid of the decimal by multiplying by 100 on both sides.

$8x+18y=450000$ ........(2)

Multiplying (1) by 8 and subtracting from (2) we get

$10y=210000$

So, y = 21000

And $x+21000=30000$

$x = 30000-21000$

So, x = 9000

Therefore, amount invested at 8% is $9000 and amount invested at 18% is $21000.
