The table below contains information on three techniques for producing $$15$ worth of bar soap. Assume that we specified $"$ $$15$ worth of bar soap" because soap costs $$3$ per bar and all three techniques produce $5$ bars of soap $($ $$15=$$$3$ per bar $5$ bars$).$ So you know each technique produces $5$ bars of soap.
