Question

Zoey read a novel in 30 days she made it a habit to read 13 pages everyday for the first 20 days. if in the last 10 days she reads 6 pages everyday how many pages are in the book?

Answer 1

320 pages.

Step-by-step explanation:

We can simply multiply and add to find how many pages are in the book.

So we have (13 pg * 20 d) + (6 pg * 10 d) = 260 + 60 = 320.

Another way of solving is to set up a proportion for both the 20 and 10 days, find how many pages are read on these days, and add:

`(13pg)/(1d)=(xpg)/(20d)\\ x=260pages\\\\(6pg)/(1d) =(xpg)/(10d)\\ x=60pg\\260+60=320`

Answer 2

Answer:320

Step-by-step explanation:

20 days times 13 pages= 260pages
10 days times 6 pages = 60pages

Total for the 30 days:
260+60= 320 pages total
