Calculating Material Variances: At Frigicor, the standard price for the M640 electrical relay (a component used in the production of a commercial refrigeration unit) is $57. Standards call for 2.5 relays per unit of finished product. In July, the company purchased 150 relays for $8,900. The company used 104 relays in the production of 50 refrigeration units (4 relays were damaged in the installation process).

Required: calculate the material price variance and the material quantity variance related to the M640 electrical relay. Indicate whether the variances are favorable or unfavorable. (show work)
