Direct Materiais Usage Variances: Direct Materials Mix and Yield Variances Energy Products Company produces a gasoline additive, Gas Gain. This product increases engine efficiency and improves gasoline mileage by creating a more complete burn in the combustion process. Careful controls are required during the production process to ensure that the proper mix of input chemicals is achieved and that evaporation is controlled. If the controls are not effective, there can be a loss of output and efficiency. The standard cost of producing a 500-liter batch of Gas Gain is $135.00. The standard direct materials mix and related standard cost of each chemical used in a 500-liter batch are as follows: usage variations at the end of each production period. Compute the total direct materials usage variance, and then break down this variance into its mix and yield components. Do not round intermediate computations and round final answers to the nearest cent. (CMA adapted)
