If a graph is prepared, with the vertical axis representing per-unit cost and the horizontal axis representing units sold, how would a line that depicts sales commissions be drawn? As a straight diagonal line, sloping upward to the right As a vertical line As a horizontal line As a straight diagonal line, sloping downward to the right A mixed cost function has a constant component of P20,000. If the total cost is P60,000 and the independent variable has the value 200, what is the value of the slope coefficient? OP600 P40,000 OP200 OP400
