Utility.consume( dict{str:num} quantities )

Sets self.utility to the value returned from self.calculate(). The model.stocks dict can be passed directly to this function.

Parameters

• quantities — dict{str:num}, required

Return Value — num

The utility gained from consuming the quantities in question.
