There are 27 & 1/3 pencils in each box. Each student will get 3 pencils per year. There will be 16 pencils left over.
I would go with D, it looks like it is the most linear out of the rest, Hope it helps:)
The point-slope form:

We have the point (1, 6) and the slope m = 7/3. Substitute:
<em>use distributive property</em>
<em>add 6 to both sides</em>
<em>multiply both sides by 3</em>
<em>subtract 7x from both sides</em>
<em>change the signs</em>

Answer:
point-slope form: 
slope-intercept form: 
standard form: 
It would be $2.40. 4 or less just ignore 5 or more add 1 more
Put common terms in evidence and simplify:
