Answer 2

$9.10.

Explanation:

We are told that Hailey paid $13 for
`1(3)/(7)` kg of sliced salami.

To find the cost of per kilogram of salami we will divide 13 by
`1(3)/(7)`

First of all we will convert our mixed fraction into improper fraction.

`1(3)/(7)=(10)/(7)`

`\text{The cost of per kg of salami}=13/{(10)/(7)`

Dividing a number by a fraction is same as multiplying the number by the reciprocal of fraction.

`\text{The cost of per kg of salami}=13*{(7)/(10)`

`\text{The cost of per kg of salami}=(91)/(10)`

`\text{The cost of per kg of salami}=9.1`

Therefore, the cost of per kg of salami was $9.10.
