1. Compute the Materials Price variance, Materials Usage variance and the Total Materials Variance
2. Compute the Labor Rate Variance, Labor Efficiency Variance, and the total Labor Variance.
3. Assume the company only investigates variances if they are $7,500 or more. Should they investigate? And if so, would the answer be different if they were to only look at the total variances?
