Answer 1

64 oz jar of peanut butter for $6.99

Step-by-step explanation:

First, determine the unit rates for the two:

`\begin{gathered} \text{16 oz jar of peanut butter for \$2}.49 \\ Unit\text{ Rate=}\frac{\text{\$}2.49}{16\text{ oz}} \\ \approx\$0.16\text{ per oz} \end{gathered}`

Similarly:

`\begin{gathered} \text{64 oz jar of peanut butter for \$}6.99 \\ Unit\text{ Rate=}\frac{\text{\$}6.99}{64\text{ oz}} \\ \approx\$0.11\text{ per oz} \end{gathered}`
`0.11<0.16`

Therefore, the better buy is a 64 oz jar of peanut butter for $6.99.
