At Greencastle, the standard price for the M640 electrical relay (a component used in the production of a commercial refrigeration unit) is $59. Standards call for 3.0 relays per unit of nished product. In July, the company purchased 156 relays for $8,736. The company used 109 relays in the production of 53 refrigeration units (4 relays were damaged in the installation process). Calculate the material price variance and the material quantity variance related to the M640 electrical relay. Indicate whether the variances are favorable or unfavorable. (Round intermediate calculations to 2 decimal places, e.g. 14.37 and nal answers to 0 decimal places, es. 125. Enter all variances as a positive number.)
