The number line below it is labeled and marked at 14, 28, 42, 56. On the left of this number line is written Price of Packs in brackets dollar sign $18, because the price of each pack is $2 $63, because the price of each pack is $7 $108, because the price of each pack is $12 $126, because the price of each pack is $14

Answer 1

Answer:  B) $63, because the price of each pack is $7

Step-by-step explanation:

Packs of Popcorn      2     4      6      8

Price of Packs           14    28    42     56

We can see that the rate is constant between each set of numbers in the table.  

$\dfrac{price}{packs}:\dfrac{14}{2}=\dfrac{28}{4}=\dfrac{42}{6}=\dfrac{56}{8}=\ 7\ \text {per pack}$

$7 per pack x 9 packs = $63
