$*$Contains direct materials, direct labor, and variable manufacturing overhead.

Janet Dunn, who has just been appointed general manager of the Westwood Plant, has been given instructions to $$get things under control.$$ Upon reviewing the plant$$s income statement, Ms$.$ Dunn concluded the major problem lies in the variable cost of goods sold. She has been provided with the following standard cost per swimming pool:

Standard Quantity or Hours Standard Price or Rate Standard Cost

Direct materials $4\mathrm{.}2$ pounds $ $2\mathrm{.}80$ per pound $ $11\mathrm{.}76$

Direct labor $0\mathrm{.}5$ hours $ $8\mathrm{.}30$ per hour $4\mathrm{.}15$

Variable manufacturing overhead $0\mathrm{.}5$ hours$*$ $ $3\mathrm{.}80$ per hour $1\mathrm{.}90$

Total standard cost per unit $ $17\mathrm{.}81$

$*$Based on machine$-$hours.

During June, the plant produced $3,000$ pools and incurred the following costs:

Purchased $17,600$ pounds of materials at a cost of $$3\mathrm{.}25$ per pound.

Used $12,400$ pounds of materials in production. $($Finished goods and work in process inventories are insignificant and can be ignored.$)$

Worked $2,100$ direct labor$-$hours at a cost of $$8\mathrm{.}00$ per hour.

Incurred variable manufacturing overhead cost totaling $$7,560$ for the month. A total of $1,800$ machine$-$hours was recorded.

It is the company$$s policy to close all variances to cost of goods sold on a monthly basis.

Required:

Compute the following variances for June:

Materials price and quantity variances.

Labor rate and efficiency variances.

Variable overhead rate and efficiency variances.

Summarize the variances you computed in requirement $1$ by showing the net overall favorable or unfavorable variance for the month.
