In order to answer this, you need a rate (i.e., $/oz) that the post office charges. That rate is basically the slope, m when you write the equation of a straight line in the form of y = mx + b. The rate differentiates the cost of a 'light' letter from a 'heavier' letter. Unless there's a flat rate or threshold in which the cost of letters weighing up the set limit is the same.
