Final answer:
To find out how many readers the 60 people who wrote letters to the editor represent as a percentage of all the newspaper readers, we can set up a proportion and solve for the total number of readers.
Step-by-step explanation:
To find out how many readers the 60 people who wrote letters to the editor represent as a percentage of all the newspaper readers, we need to calculate 4% of the total number of readers. We can set up a proportion:
Let x be the total number of newspaper readers.
rac{60}{x} = rac{4}{100}
Cross-multiplying and solving for x, we get:
60 imes 100 = 4x
6000 = 4x
x = rac{6000}{4}
x = 1500
Therefore, the newspaper has a total of 1500 readers.
