$[$The following information applies to the questions displayed below.$]$

Trini Company set the following standard costs per unit for its single product

Direct materials $(30$ pounds @ $$4\mathrm{.}40$ per pound$)$$ $132\mathrm{.}00$Direct labor $(6$ hours @ $$14$ per hour$)84\mathrm{.}00$Variable overhead $(6$ hours @ $$8$ per hour$)48\mathrm{.}00$Fixed overhead $(6$ hours @ $$12$ per hour$)72\mathrm{.}00$Standard cost per unit$ $336\mathrm{.}00$

Overhead is applied using direct labor hours. The standard overhead rate is based on a predicted activity level of $80\%$ of the company$$s capacity of $69,000$ units per quarter. The following additional information is available.

$$Operating Levels$70\%80\%90\%$Production $($in units$)48,30055,20062,100$Standard direct labor hours $(6$ DLH per unit$)289,800331,200372,600$Budgeted overhead $($flexible budget$)$Fixed overhead$ $3,974,400$$ $3,974,400$$ $3,974,400$Variable overhead$ $2,318,400$$ $2,649,600$$ $2,980,800$

During the current quarter, the company operated at $90\%$ of capacity and produced $62,100$ units; actual direct labor totaled $291,000$ hours. Units produced were assigned the following standard costs.

Direct materials $(1,863,000$ pounds @ $$4\mathrm{.}40$ per pound$)$$ $8,197,200$Direct labor $(372,600$ hours @ $$14$ per hour$)5,216,400$Overhead $(372,600$ hours @ $$20$ per hour$)7,452,000$Standard $($budgeted$)$ cost$ $20,865,600$

Actual costs incurred during the current quarter follow.

Required:

$1.$ Compute the direct materials variance, including its price and quantity variances.

$2.$ Compute the direct labor variance, including its rate and efficiency variances.

$3.$ Compute the overhead controllable and volume variances.

Part $2$: Required:

$($a$)$ Compute the variable overhead spending and efficiency variances.

$($b$)$ Compute the fixed overhead spending and volume variances.

$($c$)$ Compute the overhead controllable variance.

Compute the variable overhead spending and efficiency variances.

Note: Indicate the effect of each variance by selecting favorable, unfavorable, or no variance. Round "cost per unit" and "rate per hour" answers to $2$ decimal places.

Compute the fixed overhead spending and volume variances.

Note: Indicate the effect of each variance by selecting favorable, unfavorable, or no variance. Round "cost per unit" and "rate per hour" answers to $2$ decimal places.

Compute the overhead controllable variance.

Note: Indicate the effect of each variance by selecting favorable, unfavorable, or no variance.
