Compute the materials price variance. (Input the amount as positive value. Indicate the effect of variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Leave no cell blank - be certain to enter "0" wherever required. Omit the "$" sign in your response.) Materials price variance $ b. Compute the materials quantity variance. (Input the amount as positive value. Indicate the effect of variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Leave no cell blank - be certain to enter "0" wherever required. Omit the "$" sign in your response.) Materials quantity variance $ c. Compute the direct labor rate variance. (Input the amount as positive value. Indicate the effect of variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Leave no cell blank - be certain to enter "0" wherever required. Omit the "$" sign in your response.) Direct labor rate variance $ d. Compute the direct labor efficiency variance. (Input the amount as positive value. Indicate the effect of variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Leave no cell blank - be certain to enter "0" wherever required. Omit the "$" sign in your response.) Direct labor efficiency variance $ e. Compute the variable overhead rate variance. (Input the amount as positive value. Indicate the effect of variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Leave no cell blank - be certain to enter "0" wherever required. Omit the "$" sign in your response.) Variable overhead rate variance $ f. Compute the variable overhead efficiency variance. (Input the amount as positive value. Indicate the effect of variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Leave no cell blank - be certain to enter "0" wherever required. Omit the "$" sign in your response.) Variable overhead efficiency variance $
