Given that 11.5 ounce package costs $3.19, so the corresponding price per ounce of coffee is calculated as,
[tex]\begin{gathered} p_1=\frac{3.19}{11.5} \\ p_1\approx0.28 \end{gathered}[/tex]
Given that the second package of 30.6 ounces of coffee costs $7.98, so the corresponding price per ounce of coffee is calculated as,
[tex]\begin{gathered} p_2=\frac{7.98}{30.6} \\ p_2\approx0.26 \end{gathered}[/tex]
Comparing the unit prices, it is observed that,
[tex]p_2Since the unit price is lower corresponding to the second package, it is a better deal for a customer to buy the second package.
