Because it does not specify the order and in division, the order matters.
No. of People Cost
1 9.50
2 19.00
3 28.50
4 38.00
etc.
If we divide the cost in each row by the number of people in that row, we always have the proportion (ratio) of 9.50 / 1
We can set up a proportion, and let x be the amount 16kg would cost: 14/154=16/x. We simplify 14/154 = 1/11. Next, we cross-multiply to get (1)(x)=(16)(11), so x=176. Therefore, 16kg of apples cost $176.

Hope this helps!
Narrowing it down it's either a or c because the other 2 choices open downward (negative a).
Graphing the 2 parabolas choice c is narrower.
