Mickley Corporation produces two products, Alpha$6$s and Zeta$7$s$,$ which pass through two operations, Sintering and Finishing. Each of the products uses two raw materials$-$X$442$ and Y$661.$ The company uses a standard cost system, with the following standards for each product $($on a per unit basis$)$:

$\backslash$table$[[,$Raw Material,Standard Labor Time$],[$Product$,$X$442,$Y$661,$Sintering,Finishing$],[$Alpha$6,3\mathrm{.}0$ kilos,$3\mathrm{.}0$ liters,$0\mathrm{.}30$ hours,$1\mathrm{.}10$ hours$],[$Zeta$7,5\mathrm{.}0$ kilos,$5\mathrm{.}0$ liters,$0\mathrm{.}40$ hours,$1\mathrm{.}20$ hours$]]$

Information relating to materials purchased and materials used in production during May follows:

$\backslash$table$[[$Material$,$Purchases,Purchase Cost,Standard Price,Used in Production$],[$X$442,15,300$ kilos,$$44,370,$$$2\mathrm{.}70$ per kilo,$9,800$ kilos$],[$Y$661,16,300$ liters,$$26,080,$$$1\mathrm{.}70$ per liter,$14,300$ liters$]]$

The following additional information is available:

a$.$ The company recognizes price variances when materials are purchased.

b$.$ The standard labor rate is $$23\mathrm{.}00$ per hour in Sintering and $$21\mathrm{.}50$ per hour in Finishing.
