Question

13 berries cost $2.60 and 17 berries cost $3.06 which has the better rate?

Answer 1

17 berries which cost $3.06.

Step-by-step explanation:

If 13 berries cost $2.60, then the unit rate is calculated below:

`\begin{gathered} \text{Unit Rate=}(\$2.60)/(13) \\ =\$0.2\text{ per berry} \end{gathered}`

Similarly, if 17 berries cost $3.06:

`\begin{gathered} \text{Unit Rate=}(\$3.06)/(17) \\ =\$0.18\text{ per berry} \end{gathered}`

Since $0.18 is less than $0.2, 17 berries which cost $3.06 have a better rate.
