Restaurants frequently add an​ 18% tip on the​ pre-tax bill when the party is 8 people or more. The tax is calculated based on the bill before the tip is included. Last​ night, 10 friends went out to dinner and decided to split the bill evenly. If the bill without tax or tip was ​$114.46 and the tax was ​5%, how much did each person​ owe?
