    |dw:1434134704286:dw| The graph of the equation is of the above form. What do you think is the cost where the graph touches the y axis?

    The cost at that point is the amount to be paid, regardless of the number of shirts that are ordered. Therefore it is the 'setup fee' mentioned in the question. To find the amount of the setup fee we need to use the information that is given about the total cost of 300 shirts. Do you follow so far?
