Answer: The newspaper has 2500 readers.
Step-by-step explanation:
Given: The local newspaper has letters to the editor from 50 people.
This is the 2% of all newspaper readers.
Let x be the number of all newspaper readers.
Then. 2% of x= 50
![\Rightarrow\ 0.02x=50\ \ [\text{To remove }\% \text{we divide number by 100}]\\\\\Rightarrow\ x=\dfrac{50}{0.02}=\dfrac{5000}{2}=2500\\\\\Rightarrow x=2500](https://tex.z-dn.net/?f=%5CRightarrow%5C%200.02x%3D50%5C%20%5C%20%5B%5Ctext%7BTo%20remove%20%7D%5C%25%20%5Ctext%7Bwe%20divide%20number%20by%20100%7D%5D%5C%5C%5C%5C%5CRightarrow%5C%20x%3D%5Cdfrac%7B50%7D%7B0.02%7D%3D%5Cdfrac%7B5000%7D%7B2%7D%3D2500%5C%5C%5C%5C%5CRightarrow%20x%3D2500)
