Answer:
$2500
Step-by-step explanation:
Given that,
The lost percentage = 9%
Amount she had = $22,750
We need to find Mrs. Fisher's original investment.
As she had lost 9%, it means she will remain with 91% of her investment. Let the original investment is x.
So,
![91\%\ of \ x=22,750\\\\\dfrac{91}{100}x=22,750\\\\x=\dfrac{22,750\times 100}{91}\\\\x=\$25000](https://tex.z-dn.net/?f=91%5C%25%5C%20of%20%5C%20x%3D22%2C750%5C%5C%5C%5C%5Cdfrac%7B91%7D%7B100%7Dx%3D22%2C750%5C%5C%5C%5Cx%3D%5Cdfrac%7B22%2C750%5Ctimes%20100%7D%7B91%7D%5C%5C%5C%5Cx%3D%5C%2425000)
So, her original investment is equal to $25000.
