3. Compute the variable overhead spending and efficiency variances for the month. (Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Round "Efficiency variance" to 2 decimal places.) Variable overhead spending variance Variable overhead efficiency variance 4. Compute the fixed overhead budget and the volume variances for the month. (Round intermediate calculations to the nearest whole dollar amount. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance).) Fixed overhead budget variance Fixed overhead volume variance 5. Compute the underapplied or overapplied overhead for the month. (Round intermediate calculations and round final answer to 2 decimal places. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance).) Total variable overhead variance Total fixed overhead variance The total overhead is
