Thank you for the opportunity to help you with your question!

If the Inn charges $205.20 after a tax of 8% is implemented, what is the charge per night before the tax?

we take 205.20 = 108%

what is the 100%?

(100x205.20)/ 104 = $190 per night

Equation to the model will be:

X + 0.08X = 205.20 Answer

Please let me know if you need any clarification. I'm always happy to answer your questions.
