Answer 3

Calculating Remaining Pages to Read

To calculate the remaining pages the student needs to read, we can follow these steps:

1. Calculate the number of pages the student read on the first day. 2. Calculate the number of pages the student read on the second day. 3. Add the pages read on both days to find the total pages read. 4. Subtract the total pages read from the total number of pages in the book to find the remaining pages.

Let's proceed with the calculations.

Step 1: Calculate Pages Read on the First Day

The student read 15% of the total pages in the book on the first day.

Pages read on the first day = 15% of 160 pages Pages read on the first day = 0.15 * 160 Pages read on the first day = 24 pages

Step 2: Calculate Pages Read on the Second Day

The student read 1.5 times more pages on the second day compared to the first day.

Pages read on the second day = 1.5 * 24 pages Pages read on the second day = 36 pages

Step 3: Calculate Total Pages Read

Now, let's calculate the total pages read by adding the pages read on both days.

Total pages read = Pages read on the first day + Pages read on the second day Total pages read = 24 pages + 36 pages Total pages read = 60 pages

Step 4: Calculate Remaining Pages

Finally, we can calculate the remaining pages by subtracting the total pages read from the total number of pages in the book.

Remaining pages = Total pages in the book - Total pages read Remaining pages = 160 pages - 60 pages Remaining pages = 100 pages

Therefore, the student has 100 pages left to read.
