The standards for one carton of Wonder Wax are:Direct materials 4 lbs. @ $2.55Direct labor 6 hrs. @ $5.25Variable overhead (based on direct labor hours) 6 hrs. @ $3.40During the week ended December 4 the following activity took place: 4600 lbs. of raw material were purchased for inventory at a cost of $2.63 per pound; 1050 cartons of finished product were produced; 4225 lbs. of raw material were used; 6140 labor hours were worked at a total cost of $33463; $20569 actual variable overhead costs were incurred.Calculate each of the following variances:a. Price variance for raw materials purchased.b. Raw materials usage variance.c. Direct labor rate variance.d. Direct labor efficiency variance.e. Variable overhead spending variance.f. Variable overhead efficiency variance.G. Explain the factors that most likely caused the variances computed above:
