Part A: Assume that there is a single cause of all of the variances in Part A. State the most likely cause, and briefly explain how it possibly caused the other variances. Material Rate Material Efficiency Labour Price Labour Efficiency Variable Overhead Rate Variable Overhead Efficiency Fixed Overhead Flexible Budget Fixed Overhead Production Volume 30,000 F 20,000 U immaterial 15,000 U immaterial 22,962U immaterial immaterial Part B: Assume you are the manger of a company that installs floor tiles. The Covid pandemic has resulted in a huge increase in potential customers. In order to meet this increased demand, you purchase several new tile saws that can cut more accurately and faster. Because of this new tile saws, you can purchase slightly lower quality tiles. Labour costs per hour remains the same. The new tile saw requires the same amount of indirect material per hour as the old saw. For each of the following variances, indicate if the new saw will create a favourable variance, unfavourable variance or no variance. A. Material Price/Rate B. Material Efficiency C. Labour Price/Rate D. Labour Efficiency E. Variable Overhaed Rate F. Variable Overhead Efficiency G. Fixed Overhead Rate H. Fixed Overhead Production Volume
