If 18%x = 6.30
x = 6.30/18%
x= 6.30/0.18

Let your variable, x, equal the amount of the bill.
Then, convert 18% into a decimal.
Using a percent equation (percent * whole = part): 0.18*x = $6.30
Divide both sides by 0.18.
The result would give x on the left side of the equation, and $6.30 divided by 0.18 would be $35, your answer on the right side of the equation.
