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:
........(1)
We get the second equation as:
![0.08x+0.18(y)=0.15\times30000](https://tex.z-dn.net/?f=0.08x%2B0.18%28y%29%3D0.15%5Ctimes30000)
=> ![0.08x+0.18y=4500](https://tex.z-dn.net/?f=0.08x%2B0.18y%3D4500)
or getting rid of the decimal by multiplying by 100 on both sides.
........(2)
Multiplying (1) by 8 and subtracting from (2) we get
So, y = 21000
And ![x+21000=30000](https://tex.z-dn.net/?f=x%2B21000%3D30000)
![x = 30000-21000](https://tex.z-dn.net/?f=x%20%3D%2030000-21000)
So, x = 9000
Therefore, amount invested at 8% is $9000 and amount invested at 18% is $21000.
