An SAT tutoring service charges a $500 fee for two sessions, plus $50 for each additional session. Emily doesn't want to spend more than $700 on tutoring. What is the maximum number of additional sessions (beyond the first two) that Emily can book for her tutoring sessions

A. 4
B. 5
C. 6
D. 7

Let's say Emily books x additional sessions beyond the first two.

The cost of the additional sessions would be 50x dollars.
The total cost of the tutoring would be 500 + 50x dollars.
From the problem, we know that Emily doesn't want to spend more than $700 on tutoring.
So, 500 + 50x ≤ 700.
Subtracting 500 from both sides, we get 50x ≤ 200.
Dividing both sides by 50, we get x ≤ 4.
The maximum number of additional sessions that Emily can book is 4.
Therefore, the answer is A. 4.
