Define appropriate quantities for descriptive modeling.
Choose clear variables with units for a model
Problem
For a gym's monthly fee as a function of classes attended, define the supplied symbols \(c\) and \(F\) by role, quantity, unit, and reasonable domain.
Big Picture
What this problem is really about
Define each symbol with four pieces: its input-or-output role, the exact quantity it represents, its unit, and its context-appropriate domain. Pay special attention to how the quantity is measured: counts take nonnegative whole numbers, while a monetary output can vary continuously but should remain nonnegative here.
