Which is the better buy? a 12 pack of soda for $3.50 or a six pack of soda for $1.80? To know the better buy, find the unit rate of each.


  1. Answer: 12 for 3.50 is the better buy.
    Step-by-step explanation:
    In this question, the unit rate refers to the cost of 1 can of soda.  
    divide the cost by the quantity to get the unit rate.
    3.50/12 is about .29167 or about 29 cents.
    1.80/12 is exactly .3 or 30 cents.
    .29 < .30

  2. Answer:
    12 pack
    Step-by-step explanation:
    the 12 pack is better because if you times the six pack by 2 which is the same as the 12 pack you get $3.60 which is 10 cents more than the 12 pack.
    the price for each can is $29c
