Question

number of packs: 1, 2, 3, 4, 5, 6; number of juice boxes: 3, 6, 9, 12, 15, 18. can you extend the pattern you see above using reasoning? how many juice boxes would you have if you bought 20 packs? a 60 b 600 c 7 d 40

Explanation:

Step1: Identify the pattern

The number of juice - boxes is 3 times the number of packs. That is, if the number of packs is $n$, the number of juice - boxes $y = 3n$.

Step2: Calculate for 20 packs

Substitute $n = 20$ into the equation $y = 3n$. So, $y=3\times20 = 60$.

Answer:

A. 60
