Astore carries two different sizes of a certain brand of potato chips. bag 1 contains 8 ounces and costs $3.49. bag 2 contains 12 ounces, and costs $4.59. which bag has the lowest price per volume

The price per volume will be given by the following equation:
 P = (cost) / (volume of the bag)
 For bag 1: 
 P1 = (cost) / (volume of the bag)
 P1 = (3.49) / (8) = 0.43625 $
 For bag 2: 
 P2 = (4.59) / (12) = 0.3825 $
 We know that
 P1> P2
 
 bag 2 has the lowest price per volume 0.3825 $
