Question

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?

Answer 1

Did you figure it out???

Answer 2

Yes

Answer 3

Where are you stuck

Answer 4

the 3/8ths...

Answer 5

53+107=?

Answer 6

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

Answer 7

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

Answer 8

dude
53+117=170

Answer 9

You do the problem backwards. you start with the end and work your way forward...

Answer 10

272

Answer 11

Total number of pages in the book, we'll call that n.

n=(3/8)n+53+117=...? Algebraically manipulate the function.

Answer 12

How do I figure that out???

Answer 13

I tried but I just can't get it

Answer 14

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=...?

Answer 15

I am not sure that is correct

Answer 16

I thought that you subtracted 53 from both sides
and then divide 3/8 from both sides... Am i correct?
