Answer 1

b

Explanation:

Answer 2

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

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.

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

$7 per pack x 9 packs = $63
