Smithson, Inc. is a manufacturer of lead crystal glasses. The standard direct materials quantity is $0\mathrm{.}8$ pound per glass at a cost of $$0\mathrm{.}40$ per pound. The actual result for one month's production of $7,100$ glasses was $1\mathrm{.}8$ pounds per glass, at a cost of $$0\mathrm{.}50$ per pound. Calculate the direct materials cost variance and the direct materials efficiency variance.

Select the formula, then enter the amounts and compute the cost variance for direct materials. $($Enter amounts to the nearest cent as needed. Label the variance as favorable $($F$)$ or unfavorable $($U$),$ in the input field after the amount you enter.$)$
