The 30 pack is the better buy because each pencil is worth $0.26, while each pencil in the 12 pack is worth $0.40. To find this, you take the dollar amount and divide by the number of pencils.
7.97/30 = 0.256 (which rounds to 0.26)
4.77/12 = 0.3975 (which rounds to 0.40)

Answer:

12 pack of the same brand cost for $4.77.

Step-by-step explanation:

Given,

In first pack,

Number of pencils = 30,

Cost of the pack = $ 7.97

So, the number of each pencil = [tex]\frac{7.97}{30}[/tex] ≈ $ 0.2656

In second pack,

Number of pencils = 12,

Cost of the pack = $ 4.77

So, the number of each pencil = [tex]\frac{4.77}{12}[/tex] ≈ $ 0.3975

∵ 0.3975 > 0.265

Hence, second pack is better to buy.
