Bot GPT 3.5 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.
