When mаking decisiоns we shоuld fоcus on relevаnt informаtion (i.e. costs and benefits that differ between our alternatives).  Mistakes can be made when we make up our own decision-making rules such as 1) variable cost are always relevant and 2) fixed costs are never relevant.  To reinforce that the made-up rules above are not true, provide an example where variable costs are not relevant to a decision.
