Answer:
$13.32 for 12 candy bars $1.11 per candy bar
Step-by-step explanation:
The unit rate can be calculated as the cost divided by the number of candies. Then, the unit rate for each option is:
![\begin{gathered} \frac{\text{ \$17.12}}{15\text{ candy bars}}=\text{ \$1.14 per candy bar} \\ \frac{\text{ \$13.32}}{12\text{ candy bars}}=\text{ \$1.11 per candy bar} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/lzr6ulvdcp0cf46jbzr21y0zw87tg4nrmc.png)
Since $1.11 is lower than $1.14, the best option is $13.32 for 12 candy bars.
