Obj. $3,4$ Mackinaw Inc, processes a base chemical into plastic. Standard costs and actual costs for direct materials, direct labor, and factory overhead incurred for the manufacture of $40,000$ units of product were as follows:

$\backslash$table$[[,$Standard Costs,Actual Costs$],[$Direct materials,$120,000lbs.$ at $$3\mathrm{.}20$ per lb $.,118,500lbs,$ at $$3\mathrm{.}25$ per lb $.],[$Direct labor,$12,000hrs$ at $$24,40$ per hr $.,11,700hrs$ at $$25\mathrm{.}00$ per hr $.],[$Factory overhead,Rates per direct labor hr$.,],[$based on $100\%$ of normal,$],[$capacity of $15,000$ direct,$],[$labor hrs::$,],[$Variable cost$.$ $$8\mathrm{.}00,$$$91,200$ variable cost$],[$Fixed cost$,$ $$10\mathrm{.}00,$$$150,000$ fixed cost$]]$

Each unit requires $0\mathrm{.}3$ hour of direct labor.

Instructions

Determine $($a$)$ the direct materials price variance, direct materials quantity variance, and total direct materials cost variance; $($b$)$ the direct labor rate variance, direct labor time variance, and total direct labor cost variance; and $($c$)$ the variable factory overhead controllable variance, fixed factory overhead volume variance, and total factory overhead cost variance.
