The company has provided the following data concerning the formulas to be used in its budgeting: Fixed element per month Variable element per unitRevenue - $ 34.00Direct labor $ 0 $ 7.20Direct materials 0 12.00Manufacturing overhead 40,500 1.30Selling and administrative expenses 23,200 0.40Total expenses $63,700 $ 20.90The activity variance for selling and administrative expenses in March would be closest to:________a. $12 Ub. $12 Fc. $38 Ud. $38 F

Activity variance is the difference between the cost in the actual production and the budgeted production as a result of the differences in the level of activity consumed in a production process. It is favorable when a cost savings is recorded and unfavorable when more cost than budgeted is recorded

Budgeted production = 6,700

Actual production = 6,670

Unit rate Budgeted Actual

Selling &Admin Exp. 0.4 2,680 2,668

Fixed Selling & Admin Exp. 23,200 23,200 23,200

Total 25,880 25,868

Variance = 25880-25868 = 12 F

Note : A variance analysis is considered favorable when there is a saving in cost on the actual production.
