CollegeExplain it at college levelState the model precisely

This tool models one operating decision from explicitly supplied company assumptions. The implemented relation is Water cost per car = purchased water and sewer charges − reclaim credit ÷ washes, evaluated from Completed vehicle washes, Purchased water volume thousand gallons, Water and sewer price per thousand gallons, Reclaim-system monthly operating cost, Avoided purchased-water and sewer value to produce Water-system cost per completed car. Use metered volumes where possible and include discharge, drought and reclaim-system operating rules. The model omits unentered taxes, cash timing, legal constraints and market uncertainty. Compare the output with company records and a downside scenario before committing resources.

The decision this tool supports

Calculate metered water and sewer cost per completed vehicle wash.

Why the business model works

Use metered volumes where possible and include discharge, drought and reclaim-system operating rules.

Inputs and operating assumptions

This model uses Completed vehicle washes, Purchased water volume thousand gallons, Water and sewer price per thousand gallons, Reclaim-system monthly operating cost, Avoided purchased-water and sewer value. Keep currencies, accounting treatment and time periods consistent with one another.

The formula

Water cost per car = purchased water and sewer charges − reclaim credit ÷ washes

What the calculator produces
