Ответ:
7.97/30 = 0.256 (which rounds to 0.26)
4.77/12 = 0.3975 (which rounds to 0.40)
Ответ:
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 =
≈ $ 0.2656
In second pack,
Number of pencils = 12,
Cost of the pack = $ 4.77
So, the number of each pencil =
≈ $ 0.3975
∵ 0.3975 > 0.265
Hence, second pack is better to buy.
