We determine that by calculating the cost of buying one Oz for each case, that is:
[tex]p_1=\frac{1\cdot3}{12}\Rightarrow p_1=\frac{1}{4}\Rightarrow p_1=0.25[/tex][tex]p_2=\frac{1\cdot4}{8}\Rightarrow p_2=\frac{1}{2}\Rightarrow p_2=0.5_{}[/tex]Here p1 and p2 represent the cost of 1 Oz for the 12 Oz and 8 Oz scenarios given, from this we have that is better to buy a 12 Oz box of cereal for $3 since we would be buying 1 Oz for $0.25.
