Question

Use unit rates to determine the better buy and provide the unit price for your answer. Round your answer to the nearest hundredth, if necessary.$17.12 for 15 candy bars$13.32 for 12 candy bars

Answer 1

Answer:

$13.32 for 12 candy bars $1.11 per candy bar

Explanation:

The unit rate can be calculated as the cost divided by the number of candies. Then, the unit rate for each option is:

$\begin{gathered} \frac{\text{ \ 17.12}}{15\text{ candy bars}}=\text{ \ 1.14 per candy bar} \\ \frac{\text{ \ 13.32}}{12\text{ candy bars}}=\text{ \ 1.11 per candy bar} \end{gathered}$

Since $1.11 is lower than $1.14, the best option is $13.32 for 12 candy bars.
