Let's look at our equation,
p÷7

We must look at all our options before selecting one of them.

Can the answer be A?

Jayna does not know how many pages she needs to read. She knows she has already read for 7 days.

No that would not work,
We would have subtraction. It would look like this.
p-7.

How about B?

Jayna does not know how many pages she needs to read. She knows that she has 7 days to finish her book.

That would actually work. This is how our equation would look. 
p÷7. 
It matches the expression.

Before we make that our final answer, we should check everything else.

Here is C
C.
Jayna does not know how many days she has to finish reading. She knows she has to read 7 more pages.

That would not work.

How about D?

D.
Jayna does not know how many pages she has already read. She knows she has to read 7 more.

D is also incorrect. It would not work at all.

That means our final answer is:

B.
Jayna does not know how many pages she needs to read. She knows that she has 7 days to finish her book.

I hope that helped! :)
