Answer 2

Calculating Remaining Pages to Read

To calculate the remaining pages to read in the textbook, we can use the following formula:

Remaining Pages = Total Pages - (Total Pages * Percentage Read)

Given that the textbook has 300 pages and the student has read 15% of it, we can calculate the remaining pages as follows:

Remaining Pages = 300 - (300 * 0.15)

Remaining Pages = 300 - 45

Remaining Pages = 255

So, the student has 255 pages left to read in the textbook.
