## School_Island_sad_face 3 years ago Andreas received a new book for his birthday. He read three-eighths of the book in the first week, then fifty-three more pages in the second week. If he still has one hundred seventeen pages to read, how many total pages are in his book?

Did you figure it out???

2. SBGamer

Yes

3. SBGamer

Where are you stuck

the 3/8ths...

5. SBGamer

53+107=?

I got that 117 and 53 is 170 but I don't know what to do with the 3/8

7. SBGamer

160, therefore a number + 3/8 has to = 160, not 170

dude 53+117=170

272

Total number of pages in the book, we'll call that n. n=(3/8)n+53+117=...? Algebraically manipulate the function.

How do I figure that out???

I tried but I just can't get it

Alright, so let's start with n=(3/8)n+53+117. n is the total number of pages. We read 3/8 of n, so (3/8)n. Then we read 53 more pages. Then we still have 117 pages more to read. A total of n. Yes? Subtract (3/8)n from both sides. (5/8)n=53+117. Add the right side. 170. Divide by 5. 34. Multiply by 8. You get n=...?

I am not sure that is correct
