(a) Compute the variable overhead spending and efficiency variances. (Round "cost per unit" and "rate per hour" answers to 2 decimal places.)

(b) Compute the fixed overhead spending and volume variances. (Round "cost per unit" and "rate per hour" answers to 2 decimal places.)

(c) Compute the total overhead controllable variance.
