The following data apply to the provision of psychological testing services: Sales price per unit (1 unit = 1 test plus feedback
to client) $ 320 Fixed costs (per month): Selling and administration 22,000 Production overhead (e.g., rent of testing facilities) 15,000 Variable costs (per test): Labor for oversight and feedback 160 Outsourced test analysis 21 Materials used in testing 6 Production overhead 8 Selling and administration (e.g., scheduling and billing) 10 Number of tests per month 2,000 tests Required: Calculate the amount for each of the following (one unit = one test) if the number of tests is 2,000 per month. Also calculate if the number of tests decreases to 1,250 per month. (Do not round intermediate calculations. Round your final answers to the nearest whole dollar.)
The reason for the decision above is variances are not dependent on the direct material quantity variance and the calculation of all is differ. We also know the total direct material variance is total of material quantity & price variance that is because total variance may be favorable or unfavorable. And the option(d) direct labor efficiency variance do not relate with material variance.
