Let's represent the total number of pages as x.
The number of pages that Arlene read is 10 more than half the pages, so we can write the equation:
30 = (1/2)x + 10
To solve for x, we need to isolate it on one side of the equation. Subtract 10 from both sides:
30 - 10 = (1/2)x
20 = (1/2)x
Now, multiply both sides by 2 to get rid of the fraction:
2 * 20 = 2 * (1/2)x
40 = x
Therefore, the total number of pages is 40.
