Answer:
the amount invested at 1% = $4100
the amount invested at 9% = $2600
Step-by-step explanation:
Hello
let
A=amount invested at 1%
B=amount invested at 9%
the total amount invested is % 6700, so
A+B=6700 (1)
the profits generated by A= (c)
![c=A\frac{1}{100}](https://tex.z-dn.net/?f=c%3DA%5Cfrac%7B1%7D%7B100%7D)
the profits generated by B=(d)
![d=B\frac{9}{100}](https://tex.z-dn.net/?f=d%3DB%5Cfrac%7B9%7D%7B100%7D)
the total profit is $275,so
![275=\frac{A}{100}+0.09B\\ A=100*(275-0.09B)\\A=27500-9B\\\\replacing \ in \ (1)\\27500-9B+B=6700\\27500-6700=8B\\B=\frac{20800}{8}\\ B=2600](https://tex.z-dn.net/?f=275%3D%5Cfrac%7BA%7D%7B100%7D%2B0.09B%5C%5C%20A%3D100%2A%28275-0.09B%29%5C%5CA%3D27500-9B%5C%5C%5C%5Creplacing%20%5C%20in%20%5C%20%281%29%5C%5C27500-9B%2BB%3D6700%5C%5C27500-6700%3D8B%5C%5CB%3D%5Cfrac%7B20800%7D%7B8%7D%5C%5C%20B%3D2600)

the amount invested at 1% = $4100
the amount invested at 9% = $2600
I hope it helps
