Serving breakdown is

Amount_{serving}=\frac{A_{total}}{S}

and

Amount_{person}=\frac{A_{total}}{P}

where

S

is servings and

P

is number of people.

Notation used in the formulas: $R$ = Amount Per Serving; $x_{1}$ = Total Amount; $x_{2}$ = Total Servings; $x_{3}$ = Number of People.

Method summary: inputs are normalized to consistent units, core equations are evaluated, then secondary values are derived and rounded for display.
