Calculate variable cost variances-explain results. The standards for one case of liquid weed killer are:

Direct materials 7 lbs. @ \$9/lb.
Direct labor 4.3 hrs. @ \$19.2/hr.
Variable overhead (based on machine hours) 1.4 hrs. @ \$ 6.6/hr.

During the week ended August 6, the following activity took place:
5,054 machine hours were worked.
26,866 lbs. of raw material were purchased for inventory at a total cost of \$246,630.
3,800 cases of finished product were produced.
26,463 lbs. of raw material were used.
15,981 labor hours were worked at an average rate of \$19.5 per hour.
\$32,194 actual variable overhead costs were incurred.

Required:
Calculate each of the following variances (Input all amounts as positive values. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Round intermediate calculation to 2 decimal places and final answer to nearest whole dollar amount. Omit the "\$" sign in your response):

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. \$
