Tip formulas
\[ \text{tip} = \dfrac{\text{bill} \times \text{tip}\%}{100} \]
\[ \text{total} = \text{bill} + \text{tip} \]
\[ \text{each person pays} = \dfrac{\text{total}}{\text{number of people}} \]
For a quick mental estimate, move the decimal one place left to get 10%, then double it for 20% or add half of it for 15%.
