Answer 1

$3.90 was the cost of salami per kilogram.

Explanation:

The question is incomplete, so the complete question is below:

`Hailey\ paid\ \$13\ for\ 1\ 3/7\ kg\ of\ sliced\ salami.\ \\What\ was\ the\ cost\ per\ kilogram\ of\ salami?`

Now, to find the cost of salami per kilogram.

Cost of
`1(3)/(7)` kilogram of sliced salami = $13.

Now, to get the cost of salami per kilogram we use unitary method:

If, the cost of
`(10)/(3)` kilogram of salami = $13.

Then, the cost of 1 kilogram of salami =
`(13)/((10)/(3))`

`=(13)/(10)* 3`

`=(39)/(10)`

`=\$3.90.`

Therefore, $3.90 was the cost of salami per kilogram.
