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 $-x442$ 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$6,2\mathrm{.}5$ kilos,$2\mathrm{.}5$ liters,$0\mathrm{.}10$ hours,$1\mathrm{.}00$ hours$],[$Zeta$7,4\mathrm{.}5$ kilos,$5\mathrm{.}0$ liters,$0\mathrm{.}30$ 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$442,15,200$ kilos,$$42,560,$$$2\mathrm{.}60$ per kilo,$9,700$ kilos$],[$Y$661,16,200$ liters,$$24,300,$$$1\mathrm{.}60$ per liter,$14,200$ liters$]]$

The following additional information is available:
