Let's look at our equation,
<span>p÷7

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

Can the answer be A?

</span><span>Jayna does not know how many pages she needs to read. She knows she has already read for 7 days.
</span><span>
No that would not work,
We would have subtraction. It would look like this.
p-7.

How about B?

</span><span>Jayna does not know how many pages she needs to read. She knows that she has 7 days to finish her book.
</span><span>
That would actually work. This is how our equation would look. 
p</span>÷7. 
<span>It matches the expression.

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

Here is C
</span><span>C.
Jayna does not know how many days she has to finish reading. She knows she has to read 7 more pages.
</span>
That would not work.

How about D?

<span>D.
Jayna does not know how many pages she has already read. She knows she has to read 7 more.
</span>
D is also incorrect. It would not work at all.

That means our final answer is:

<span>B.
Jayna does not know how many pages she needs to read. She knows that she has 7 days to finish her book.
</span>
I hope that helped! :)
