Answer:
Let x = the charge in 1st city before taxes
Let y = the charge in 2nd city before taxes
  
  
Set up equation before taxes.
  
y = x - 1500        eq1
  
  
Set up equation for total tax paid.
  
0.065x + 0.06y = 378.75         eq2
  
  
Substitute eq1 into eq2.
  
0.065x + 0.06(x - 1500) = 378.75
0.065x + 0.06x - 90 = 378.75
0.125x - 90 = 378.75
0.125x = 468.75
        x = 3750
  
Substitute this value of x into eq1.
  
y = 3750 - 1500
y = 2250
  
  
The hotel charge in city one is $3750 and the hotel charge in city two is $2250
