Fortes Incorporated has provided the following data concerning one of the products in its standard cost system. Variable manufacturing overhead is applied to products on the basis of direct labor-hours.

Inputs	Standard Quantity or Hours per Unit of Output		Standard Price or Rate
Direct materials	7.1	ounces	$ 7.30	per ounce
Direct labor	0.6	hours	$ 26.70	per hour
Variable manufacturing overhead	0.6	hours	$ 5.60	per hour

The company has reported the following actual results for the product for April:

Actual output	8,550	units
Raw materials purchased	61,710	ounces
Actual cost of raw materials purchased	$ 341,700
Raw materials used in production	60,735	ounces
Actual direct labor-hours	3,850	hours
Actual direct labor cost	$ 107,860
Actual variable overhead cost	$ 20,701

Required:

a. Compute the materials price variance for April.

b. Compute the materials quantity variance for April.

c. Compute the labor rate variance for April.

d. Compute the labor efficiency variance for April.

e. Compute the variable overhead rate variance for April.

f. Compute the variable overhead efficiency variance for April.

(Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Input all amounts as positive values.)
