Answer 2

Calculation of Remaining Pages to Read

To calculate the number of pages that Alesha has left to read, we need to determine the total number of pages in the book. We know that Alesha has already read 90 pages, which is one-third of the entire book, and an additional 150 pages over the weekend.

Let's calculate the total number of pages in the book:

1. Alesha has read 90 pages, which is one-third of the book. 2. Therefore, the total number of pages in the book is 90 * 3 = 270 pages.

Now, let's calculate the number of pages Alesha has left to read:

1. Alesha has already read 90 pages. 2. Over the weekend, he read an additional 150 pages. 3. Therefore, the total number of pages Alesha has read is 90 + 150 = 240 pages. 4. To find the number of pages he has left to read, we subtract the pages he has read from the total number of pages in the book: 270 - 240 = 30 pages.

Therefore, Alesha has 30 pages left to read.
