Calculate the direct material price variance, the direct material efficiency variance, the direct labor price variance, and the direct labor efficiency variance for each of the product lines separately. Also, for each overhead activity, calculate the FMOH (spending and production volume) variances for the Pen division and the VMOH (spending and efficiency) variances for the two products Use IF statements to determine if the variances are favorable Or unfavorable b. Which of the variances. that you calculated reasons for the variances should you investigate - and why? Provide possible
