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.

The difference in mail handled between 195 and 1965 is -5.4 x 10
<h3>What is the difference in mail handled?</h3>
The data on the pieces of mail handled by the United States Postal Service is written in scientific notation. Scientific notation is used to compress larger numbers into smaller numbers.
In order to write a number in scientific notation, the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10. For example, 1 x 10² is equivalent to 100
Difference in mail handled = mail handled in 1995 - mail handled in 1965
(1.8 x
) - (7.2 x
)

Answer:
A = -68.75p +2906.25
Step-by-step explanation:
We can solve for m and b using the given values of A and p.
1600 = m·19 +b
2150 = m·11 +b
Subtracting the second equation from the first, we have ...
-550 = 8m
m = -550/8 = -68.75
Substituting this into the first equation gives ...
1600 = 19·(-68.75) +b
b = 1600 +1306.25 = 2906.25
The desired linear equation is ...
A = -68.75p +2906.25
