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! :)
