# BOM and assembly unit-cost estimate
# Scope: Two line-item BOM with supplied scrap allowance; account units.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

quantityA = 4
costA = 2
quantityB = 2
costB = 5
scrapFraction = 0.05

netCost := quantityA*costA+quantityB*costB
purchaseCost := netCost/(1-scrapFraction)

check unit BOM budget: purchaseCost <= 25

scenario alternative: quantityA = 3.2
