Kelly Clarkson manufactures a number of products. The standards relating to one of these products are shown below, along with actual cost data for May.

	Standard Cost per Unit				Actual Cost per Unit
Direct materials:
Standard: 1.80 feet at $3.00 per foot	$	5.40
Actual: 1.75 feet at $3.20 per foot					$	5.60
Direct labor:
Standard: 0.80 hours at $17.00 per hour		13.60
Actual: 0.85 hours at $16.40 per hour						13.94
Variable overhead:
Standard: 0.80 hours at $4.00 per hour		3.20
Actual: 0.85 hours at $3.60 per hour						3.06
Total cost per unit	$	22.20			$	22.60
Excess of actual cost over standard cost per unit			$	0.40

The production superintendent was pleased when he saw this report and commented: "This $0.40 excess cost is well within the 2 percent limit management has set for acceptable variances. It's obvious that there's not much to worry about with this product."

Actual production for the month was 15,000 units. Variable overhead cost is assigned to products on the basis of direct labor-hours. There were no beginning or ending inventories of materials.

Required:

1.	Compute the following variances for May:

a.

Materials price and quantity variances. (Input all amounts as positive values. Leave no cells blank - be certain to enter "0" wherever required. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Omit the "$" sign in your response.)

b.

Labor rate and efficiency variances. (Input all amounts as positive values. Leave no cells blank - be certain to enter "0" wherever required. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Omit the "$" sign in your response.)

c.

Variable overhead rate and efficiency variances. (Input all amounts as positive values. Leave no cells blank - be certain to enter "0" wherever required. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Omit the "$" sign in your response.)

2.

How much of the $0.40 excess unit cost is traceable to each of the variances computed in (1) above. (Input all amounts as positive values. Leave no cells blank - be certain to enter "0" wherever required. Round your answers to 2 decimal places. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Omit the "$" sign in your response.)

3.

How much of the $0.40 excess unit cost is traceable to apparent inefficient use of labor time? (Input all amounts as positive values. Leave no cells blank - be certain to enter "0" wherever required. Do not round intermediate calculations. Round your answers to 2 decimal places. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Omit the "$" sign in your response.)
