[Solved] Standard and actual costs for direct materials for the manufacture of 2,000 units of product were as follows: \[\begin{array} { l l } \text { Actual costs } & 2,750 \mathrm { lbs } . @ \$ 8.10 \\ \text { Standard costs } & 2,800 \mathrm { lbs } . @ \$ 8.00 \end{array}\] ? Determine the (a) quantity variance, (b) price variance, and (c) total direct materials cost variance.
