Hailey paid \[\$13\] for \[1\dfrac{3}{7} \text{ kg}\] of sliced salami.

**What was the cost per kilogram of salami?**

\[\$\]

To find the cost per kilogram of salami, we can divide the total amount Hailey paid by the weight of the salami.

Given:
- Total cost: \$13
- Weight of salami: $1 \dfrac{3}{7} \text{ kg}$

First, convert the mixed fraction $1 \dfrac{3}{7}$ into an improper fraction:

\[
1 \dfrac{3}{7} = \frac{7 \times 1 + 3}{7} = \frac{10}{7} \text{ kg}
\]

Now, to find the cost per kilogram, divide the total cost by the weight:

\[
\text{Cost per kilogram} = \frac{13}{\frac{10}{7}} = 13 \times \frac{7}{10} = \frac{91}{10} = 9.10
\]

So, the cost per kilogram of salami is $\$9.10$.
