 Sales = 0.150x – 28000 In this case, the values are given in thousands (i.e., the cost of making one unit will be $150 with $28,000 in fixed sosts, such as space rent, utilities, etc. What does the graph look like for equation? Or what do I label the x- and y-axis values on the graph? I think I understand that the slope is the cost per unit = 150 and the y-intercept is the fixed overhead cost = 28000. I think I'm almost there, but not sure how to graph or what it is supposed to look like. Any clues, hints or examples would be appreciated  |

Seems to me that the equation should be: y=150x-28000, where y is the profit (or loss). Use our basic graphing calculator and enter: 150x-28000. The graph will label the intercepts automatically and the x-intercept will be the point of interest, that is, where is the break even point (when cost is 0). This shows how many units must be sold to get a positive profit. ---------------------------------------- Principal Skinner |

Ah yes, I mistakenly left the decimal point in. Thanks, that's where I got messed up.  |
