<p>I will post the answer later, I first want to see if you pick my answer or the right one.</p>

<p>I would guess 5/40 or 0.125, that is to say option C. Not sure if I'm right...</p>

<p>Is it 3/25 or .12</p>

<p>5/40 is correct.</p>

<p>it's basically asking for the slope. u see at the top right hand corner, where it went thru (40,5).
so 5/40 is correct, because it's an exact number, u can also try others,by estimating. 3/25 is also a good one,but not exact enough,but close enough to get u the right answer.</p>

<p>Yeah, C is the right answer. So I really got this wrong. Thanks!</p>

<p>idk how you guys did it, but i did it a way easier way. the best fit line intersects right at $3 per 25 ounces. I just divided 3 by 25 and got 0.12, C.</p>

<p>EDIT: oh wait i think ivy did that too</p>

<p>^ if the answer choices were all .12ish , then what would u do lol
well apparently thats not the case, it wont happen on SATs, 3/25, though leads to the correct answer, its not 100% accurate. 5/40 might not be perfect,but its better than 3/25</p>
