including a 5% sales tax, an inn charges $189 per night. find the inns nightly cost before the tax is added. the inns nightly cost before tax is added is $□.

Answer

Explanation:

Step1: Let the cost before tax be $x$.

The total cost including 5% tax is $x + 0.05x=1.05x$.

Step2: Set up the equation.

We know that $1.05x = 189$.

Step3: Solve for $x$.

$x=\frac{189}{1.05}=180$.

Answer:

$180$
