.

If the number  6  in your formula represents  $6  tax per each room per night,
then the formula for the total cost is written incorrectly.


I do not understand,  what about the domain I can/should discuss regarding an incorrect formula.

Cost is then 69+6=75 dollars per night for each room. This is a RATE.
If r number of rooms and n number of nights, then cost is r%2An%2A75.
What domain you are looking for is not clear. If it is how many rooms, then r is from {10,11,12,13,14,15,16}.
