Two different but comparable brands of canned milk are sold in a grocery store. brand A contains 3 1/2 liters and sells for 25.00. Brand B contains 2 1/4 and sells for 18.00. which is the better buy?

Answer 1

To determine which is the better buy, you need to calculate the unit cost (price per Liter) To do this you divide:

Brand A: 25/3.5 = $7.14/L

Brand B: 18/2.25 = $8.00/L

Brand A is the better deal
