Answer 1

The mobile company charges $3 for an hour of service.

Answer 2

Answer: There are $3 charged every minute from customer.

Explanation:

Amount charges per an hour = $180

As we know that

1 hour = 60 minutes

For 1 hour, amount would be $180

For 60 minutes, amount would be $ 180.

We will use "Unitary method":

For 1 minute, amount would be

`(180)/(60)\\\\=\$3`

Hence, there are $3 charged every minute from customer.
