<span>y=-0.7/x The lines of the graph are located in Quadrant II and Quadrant IV; asymptotic at 0.7. The Graph in Q II is asymptotic only at quadrant II; Q IV at quadrant IV. The line of reflection is diagonally crosses from QIII -> point of origin -> QI
More or less, </span>y=-0.9/x has the same characteristic as y=-0.7/x but <span>y=-0.9/x is asymptotic at 0.9</span>
The materials price variance is usually the responsibility of the purchasing manager. The materials quantity and labor efficiency variances are usually the responsibility of production managers and supervisors.
so... that'll give you the hourly charges now, he also charges a $60 fixed amount so, whatever you get in hourly charges, add 60 to that, and that's the total bill
