Miller Toy Company manufactures a plastic swimming pool at its Westwood Plant. The standard cost for one pool is as follows:

	Standard Quantity or Hours		Standard Price or Rate			Standard Cost
Direct materials	1.60	kilograms	$5.00	per kilogram	$	8.00
Direct labour	0.90	hours	$5.00	per hour		4.50
Variable manufacturing overhead	0.40	machine-hours	$2.00	per machine-hour		0.80
Total standard cost					$	13.30

The plant has been experiencing problems for some time, as is shown by its June income statement when it made and sold 15,200 pools; the normal volume is 15,350 pools per month. Fixed costs are allocated using machine-hours.

Janet Dunn, the general manager of the Westwood Plant, wants to get things under control. She needs information about the operations in June since the income statement signalled that the problem could be due to the variable cost of goods sold. Dunn learns the following about operations and costs in June:

a.	31,500 kilograms of materials were purchased at a cost of $4.10 per kilogram.
b.	24,500 kilograms of materials were used in production. (Finished goods and work-in-process inventories are insignificant and can be ignored.)
c.	11,900 direct labour-hours were worked at a cost of $8 per hour.
d.	Variable manufacturing overhead cost totalling $14,184 for the month was incurred. A total of 5,910 machine-hours was recorded.
It is the companys policy to close all variances to cost of goods sold on a monthly basis.

Required:

1.	Compute the following variances for June:
a.	Direct materials price and quantity variances. (Indicate the effect of each variance by selecting "F" for favourable, "U" for unfavourable, and "None" for no effect (i.e., zero variance).)

b.	Direct labour rate and efficiency variances. (Indicate the effect of each variance by selecting "F" for favourable, "U" for unfavourable, and "None" for no effect (i.e., zero variance).)

c.	Variable overhead spending and efficiency variances. (Indicate the effect of each variance by selecting "F" for favourable, "U" for unfavourable, and "None" for no effect (i.e., zero variance).)
