In city one, the hotel charges before taxes were $5,250.
In city two, the hotel charges before taxes were $6,750.

The tax in the first city was 5 %, and the tax in the second city was 8.5 %.
The total hotel tax paid for the two cities was $ 836.25
5% of x + 8.5% of y = $836.25
...[2]
Now putting value of y from [1] in to [2]:
On solving we get :
x = $5,250
Using vakue of x in [1] to find y:
In city one, the hotel charges before taxes were $5,250.
In city two, the hotel charges before taxes were $6,750.
