Trade records may use local units and varied payment systems. Use only the exchange rule supplied here, not a claim about universal historical prices. Barter and currency can coexist. These are fictional teaching ledgers, not actual market records.

Worked example

At a stated rate of 3 grain measures per cloth piece, 4 cloth pieces cost 12 grain measures. The rule applies only to that model.

A fictional three-row ledger gives four cloth pieces, three grain measures per cloth piece, and a cost of twelve grain measures. Historical units and prices were not universal; use the rule stated in each question.
