Problem 4-1 Variable and Fixed Cost Pattern Analysis The cost behavior patterns below are lettered A through H. The vertical axes of the graphs repres dollars of expense, and the horizontal axes represent production in units, machine hours, or direct hours. In each case, the zero point is at the intersection of the two axes. Each graph may be used than once.
