In this case, what we must do is calculate the price per unit each one:
[tex]\begin{gathered} 1\text{cup}=8ounce \\ \frac{8.28}{36}=0.23 \\ \frac{5.76}{6\cdot8}=0.12 \end{gathered}[/tex]therefore, the second purchase is better because it cost $0.12 per ounce, otheriwse the other purchase compares that they are $0.23 per ounce
