Answer: There are $3 charged every minute from customer.
Step-by-step 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
[tex]\dfrac{180}{60}\\\\=\$3[/tex]
Hence, there are $3 charged every minute from customer.
