Answer:
The amount before tax at the first hotel be x = $3500
The amount at the second hotel will be x+500 = $4000
Explanation:
Let the amount before tax at the first hotel be x
The amount at the second hotel will be x+500
The tax in the first city was 5.5% = 0.055
the tax in the second city was 7.5% = 0.075
Hence, we have
0.055(x) + 0.075(x + 500) = $492.50
0.055x + 0.075x +37.5 = 492.50
0.13x = 492.50 -37.5
0.13x = 455
x = 455/0.13
x = $3500
The amount before tax at the first hotel be x = $3500
The amount at the second hotel will be x+500 = $3500 + $500
= $4000
