# Tooling versus unit-cost break-even
# Scope: Fixed tooling cost versus per-part savings; currency is dimensionless account units.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

tooling = 10000
alternativeUnit = 20
moldedUnit = 5

savings := alternativeUnit-moldedUnit
quantity := ceil(tooling/savings)

check positive unit savings: savings > 0

scenario alternative: tooling = 8000
