Answer:
$175/night
Step-by-step explanation:
The charges of an inn for one night including sales tax = $189
The sales tax rate = 8%
Let the charges of the inn before adding tax be 'x' per night.
The charges of inn before tax = x + (8% Ă— x) = 189

1.08x = 189
x =

x = $175
The charges are $175/night before tax is added
