Answer to Problem 48MR
Explanation of Solution
Given:
In a recent year, 57 million American adults read online blogs. However, 45 million fewer American adults say that they maintain their own blog
Concept Used:
57 million American adults read online blogs and 45 million fewer American adults say that they maintain their own blog The numbers of American adults maintain their blog means the difference between the number of American adults read online bogs and the numbers of adults maintain their own blog.
Calculation:
Let the number of American adults maintain their own blogs =
Thus, the required equation is
